Dyno'd @ 334 WHP & 5 lbs. of Boost - Dissappointed

[joeyb]

Took my car to ABEL RACING in OKC today and finally got the bitch on a dyno...first time/cherry popped/etc.....now - there is good news, bad news, and realistic news.

**I had one pull w/ the filter off @ 347 - but this is what they printed out for me so that is what I am posting:



I in no way thought my shit was actually tuned to 400whp, but 334 is definitely lower than I was hoping for. HOWEVER - this is about a "70%" tune to be safe and as we tried to increase above this, I began to lean out and couldn't deliver enough fuel.

We tuned for a couple hours, and in the end the badass motherfucker that tuned my car said it was the fuel pump and the injectors that were holding us back after about 5K.

these need to be upgraded, and after 5K it was not safe nor able to push past about 4.5 lbs. I told them I already had the injectors and they said they'd order me a fuel pump and then it would be safe.

they also recommended an intercooler for anything over 10 lbs for sure, and said they thought the methanol spray cooling kit was all but worthless...

the good news was the guy said I went from an absolute "shit tune" to a "very very close" one and on the way home I could tell. It used to be sluggish and way too rich and now it purrs like a kitten - but I can't open it up completely until I get the fuel delivery worked out.

the first run I laid down was 271 whp - and like I mentioned above, one of them was 347 by the end....and as tanner pointed out to me in an IM that has to be CLOSE to 400 at the crank.....so I guess I should be happy and I am - at least I am tuned up proper now, not just dumping fuel into the engine, and know where I stand as far as increasing my performance from here.

[PopsGT]

Props to being resolute!

[zumspeedsupra]

Wow, great news man. Hope you get the fuel delivery solved and get her running even faster! Very impressive

[Chaos]

Pimp dude! 330whp is still impressive. The point isn't peak whp its if its usable. And sounds like it is

[kazman]

good news joe!

[Freeker]

shouldn't be disappointed dude... still very impressive

[HAHA NO]

yeah man..still freat numbers, and like you said only 70% complete so you know there is more available

[TwilsonD7]

That's 100hp over stock to the wheels...more boost, meth cooler and a better tune you can grab another 100hp

[trevroar]

That's a nasty drop in boost between 70-80mph... what was happening there?

[muscles]

$ICKK. at least you know where you stand now/

That honestly looks like the shift from 2nd to 3rd. I've seen this issue while drag racing already at the local track. I was running 1/8th miles and the shift from 2nd to 3rd would usually drop me out of MIVEC and make the car slightly sluggish...

Once you go from 2nd to 3rd I've gone from 6.5k to like 3.8-4k rpm...That could be his boost loss

[ALBOE]

was it dyno'ed on 4th gear or 3rd gear?

[gsxtt]

good to see you got your numbers down on paper now

THANKS SO MUCH all of you for the kind words fellas. truly that makes me feel WAY better - ha I almost didn't post this thread. you're all right of course; and 333 is plenty for a first go, and it felt great driving home just knowing the tune was correct, and feeling the car run the way it's suppose to even with the super charger on there. I'm the one who always acts like I don't care about track times or dyno #s, but after the time and $ I put into the car, I was like WTF?!?! when I saw 'max power 271' come up after that first pull. I was like 'what the hell is this piece of shit?' or 'jeez where did I mess this all up?' but that was before I had given the man a chance to work!

He got rid of my 'system too rich' codes, but another one started. He said I may also have to clamp the MAP (in addition to the MAF already being clamped) which I believe you can actually do with the F/IC 6 but you have to use one of the Auxliary wires to do so - but I didn't think of that until I had left. it's a MAP sensor code now that the ECU is seeing some actual boost - and it appears now that the ripp bratt box was actaully doing something....WOW I know...so I may have to either set up the F/IC to do it or put the bratt back in.

Will may very well be right w/ his answer above about shifting, but I was also having trouble with belt slippage the whole time - so that may be it also. I tightened it down some more on the dyno and got the 'squeal' to completely go away even at high RPMs but I/they still thought there may have been some slippage. I will try to tighten more before I go in again, and probably just need to put a new one on there. and like I'm about to mention below - I was not actually behind the wheel for the pulls, so I am not sure how smooth/perfect he was getting the shifts, etc.

he was actually on the phone w/ ripp at one point and I heard him tell them that everything looked and sounded good. he said the linkages all felt good and tight, and the chance of a boost leak at least from the blower to the throttle body was very small and all the mechanical work looked good - so that made me blush a little - cause this guy was very cool, very knowledgable, and absolutely objective and indifferent about my car. shit they seriously had 10 other eclipses there - 1,2, and 3gs - all of them boosted or in the process of being boosted. they had a mean vett, cobra, nova, I saw a talon that had a HUGE turbo set-up on it w/ a massive exhaust pipe right out the front of side of the car in front of the left front tire - track only, obviously! the place was very very impressive and they are the DSM experts around the OKC metro. I am just stupid for only just now going to them.

I will get pics next time I go up there - when I probably have them do the injector, MAP clamp, fuel pump, and re-tune.

I honestly don't know 100% for sure as I was not behind the wheel for the pulls, the guy never said, and I never asked. But I pretty sure they were all 4th gear pulls. I'd hear him go quickly through 1 and 2 and I'm pretty sure 3 - so 99% sure they were 4th.

man but those guys acted like the meth cooling was just not the way to go - especailly over 10 lbs....anyone else have an opinion? I'd love to make the meth cooler work if there is any chance at all - but these guy look like they have turboed more cars than they can remember, and are saying over 10 lbs would need/benefit/must have an intercooler.

I said: 'wouldn't that take away performance almost to the point of not making it even worth having the sc anymore?'
he said probably not - turn up the boost, but I am not sure if he understood the mechanical limitations of the ripp kit. he also smartly suggested another tensioner pulley that I would have to have them make and install - wrapping the belt more fully around the pulley on the SC drive shaft - giving it more surface to grab and less slippage, etc....so I may have to at least try that.

thanks Matt! bout time huh? well hopefully I will have them improved at least a little by the time you get back

[trevroar]

I don't think that drop in boost was due to a shift, I've never seen anyone shift during a power pull on a dyno. Another reason I don't think there was a shift is because your AFR's didn't spike to lean as it would during a shift.

[dejectedangle]

Personaly I'm doing a intercooler only because meth is just one more fucking thing to tune and lol intercoolers never run out of meth..... The only downfall is maybe a little lag to a intercooler

[TwilsonD7]

I want to see an intercooler, everyone says there's not bought air...does yours only boost at wide open throttle?

[deprydation]

You know that's true. I have seen some shifting through the first couple gears on a power pull, but the AFR didn't drop at all. I failed to notice this. My fault...

The only other thing it could have been than is belt slippage. I could see the belt slipping somewhere in that RPM range because of engine rock or something related.

You've done poly engine mount bushings and the stiffy right???


By the way, that setup and power numbers are impressive. If only we could have our cars like 1000 pounds less or so.

[dejectedangle]

Umm if I don't get enough air I'm buying vortech v1 s-trim it's good to 26 lbs and will fit directly on out bracket

[roy_robinsonV]

its all good joey

[Freeker]

Joe... intercooler dude... nothing looks more bad ass on a car than an intercooler... dude... dude... for real... intercooler

[roy_robinsonV]

ya dude^^ fo sho dude IC= bad ass

not to thread jake but roy did you ever buy that ported TB?

[joeyb]

thanks bro. yeah I was really good about not getting my hopes up too much but then started thinking 'well shit MAYBE it's closer than I think!' since I had been running so rich I thought I'd tune right up to close to at least 350. but once I get the injectors in and a new fuel pump, I should certainly be able to squeeze a little more out I think and hit 350.

yeah I'm sure you are right, man. that belt slips like a mother fucker under boost if I don't have it tight as hell. it's definitely a problem and probably something that this kit will suffer from/have to deal with, but maybe not. I'm going to try a new belt at least and someone told me about these stronger belts that have horizontal cross traction or something, so I may have to try to hunt those down if they even exist

well, the guys up at ABEL sure made it sound like the way to go...but it will be a tough build for me and cost another $1000 to have them do it probably....jeez. like I need something to spend ANOTHER THOUSAND on....GOD DAMN IT. but I'll probably wind up doing it if someone can't get this meth going for me and make me feel good about it.

oh fuck yeah I got those mounts and the stiffy. I watched my motor as he pulled and it held in there DAMN TIGHT and only rocked (not even THAT bad) at the very highest end. that motor is in there tight like a bitch. I am 99% sure I can tighten the belt more...I think...I hope....I'll buy a new one....and add another tensioner pulley if it looks like that would help - and it does
thanks for the props, tho, man. I am feeling way better about the #s today

well I am glad to know there is an option for us - probably another several thousand dollars tho I bet..shit if I can just get 8 - 11 lbs and have a motor tough enough to handle a 120 shot also - I'll be happy and content and never spend another dollar on my car....ok well 2 of those 3 are true.

yeah I watched what he was doing and he had a trigger in his hand and wouldn't trigger the log sample start until he had it in 4th and would then just rip it open to the top....
you know, I am almost thinking he may have done 5th gear pulls or does that sound stupid?

[joeyb]

yeah roy, jeff, I was just thinking (well have been since I was up at that shop yesterday) that an intercooler would be pretty damn...well, you know, cool. I guess dejected should be able to tell us if it works or not - but if I could get that meth to work that would certainly be the cheaper way to go for me

[Lanzerralliart]

Niceeeeee keep it up......

Can you hit 100mph in third gear at redline, if not, then it was probably done in 4th gear. Doubt they did a 45mph pull in 5th..... ehh what do i know - I drive a GS!!!

[groundpounder]

Your average rear wheel drive will lose on average 17.6 percent hp fro fly wheel to tires, on as a front wheel drives it's bout 10 percent so ur bout 381 hp at the fly wheel give or take. An ls1 corvette puts out 350 at the fly wheel - 17% to the wheels ats 288p at the wheels . Congrats u just smoked an ls1 corvette with ur 347 rwhp.

[joeyb]

^haha well that WOULD be something if I could do it on the street or at the track and get it on camera!...until then...these are some numbers on a piece of paper - but I appreciate the effort, man

and quoting that 347 pull is tough to do since we couldn't seem to get it up there again, the average was 327 - 335 pretty consistently w/or w/out the filter on there. BUT once I get the new fuel delivery parts installed and re-tuned, one would certainly THINK I could get back up to 350 on a consistent basis.

hey thanks daniel! at least it's a starting point, and I just have to be patient with this build

[Ballfade]

keep pushin it!

[trevroar]

Thanks for the e-rep Joey!

[dejectedangle]

E bay intercoolers and piping all under 200.00........ I'm installing my setup as we speek

well shit man that sure sounds a lot better than the $1000 the guys at abel were telling me for a custom cooler built and installed. we looked briefly at the space under there and there sure isn't much room to work with...are you cutting anything out or moving anything to make room? I'm very excited to see if this works out, maybe it will solve some of our problems....

[majin]

Joey, watch out for valve float with higher boost...

[joeyb]

^hey thats a good point man, thanks for reminding me. that had not entered into my head...not that much does. no, I plan to get an upgraded spring/valve/retainer kit for when I build out this motor. hell I guess I could get those in by themselves w/out too much trouble, right?
