Supercharger

[Famous8618]

So...im thinkin of putting the RIPP MODS Supercharger on my GT.....BUT! I hear that my engine can only hold up to 10 maybe 12 pounds cuz of the alluminum block...and that if i wanted to turbo or supercharge it will need the steel block...true or false?

[Tech_Greek]

We have a cast iron block, I believe they're up to 8 Psi safely right now.

The older 6G72 motors had issues with the pistons at a certain HP.

For now, you're fine, unless you want an all out drag FWD car on slicks going to work everyday.

[bmshue51]

Im pretty sure you would need the steel block... and just my preference I wouldnt go with RIPP on the supercharger... I talked to the guys at Buschur Racing and they are friends with that guy who has the 4G Turbo kit for sale... ddynopower.com - they said he knows what hes doing and his kits are awesome... Id go with the turbo kit...

[Tech_Greek]

There's no steel block.

You have a cast iron block and aluminum heads...the ONLY problem that might happen from this is that the rate at which cast iron and aluminum cools is a little bit different and thus if you over heat your motor the heads can actualy warp enough to cause a head gasket leak leading to head gasket failure, a VERY very common issue on Thunderbird Supercoupes whom used the same components.

Who's "that guys turbo kit"? I've only seen two turbo kits, one very well put together by RRE, and one piss poor one built that was put on crashes car that he had to take off anyone because it was never finished.

So...with that being said, if anyone else has any turbo kits out, please post pictures, and specifications...

There's NOTHING WRONG, with a supercharger...it's all about determing where you want to go with your car, if you want all out brute power then go for the turbo charger, but if you're wanting a daily driver that has a bolt-on kit, go for the supercharger option...for NOW, there are no bolt on turbo kits avaliable, everything is either custom made to your car or a one off special.

Yea but it doesn't really say anything about the kit.

[sullysdetailing]

it says nothing about the 4g kit

[tjh]

I read in one of the 4G forums that that company(ddynopower) kits are not that good and is not recommened

[Famous8618]

Well wud it be a good idea of me putting the supercharger even on? and i knw ill need the headers...(if they are good from rippmods.com) BUT is there anything else i need? and right now i have a alluminum block right?

[Tech_Greek]

That's all up to you hoss, just depends.

* Are you wanting a top speed beast, and willing to wait for a turbo kit, and do supporting mods up until that point.

or

* Are you wanting a reliable daily driver with extra umph in it, that you can have support.

[360jeepboy]

And no you don't have a aluminum block.... it is cast iron!

I just asked some other people and got a complete opposite answer from 5+ people. All of them being passed DSM owners or current EVO owners who all had glowing things to say about him.

This guy used to be with Buschur (and apparently still is to some extent, he has tight connections) and has been around since the early 90s doing what hes doing. He likes to keep a low profile because he likes to stay comfortable with the amount of work he is doing. Say what you want about that, but this guy has apparently been around a long time and knows his shit.

In the short time i've been looking up info on him and his product i've seen nothing but good comments. If I was in the market I would at least talk to this guy and get some info.

[sullysdetailing]

is there any info on the kit that is suppost to be for the gt 4g??

[Tech_Greek]

I've heard very good things about him as well, but he dosn't even come close to mentioning anything about a 4G on the page.

Maybe it's a one off thing, best bet would be to call him.

[XFactor]

On his site there isn't any info other than mentioning he has it available.

I sent him an email like mid day yesterday hoping to get some specifics, like what turbo he's using and some other specs, no reply yet, but it's still early monday morning, I wouldn't expect a reply until later in the week, especially if he's a small shop.

If I get any info i'll pass it on. But i'm not really looking to do anything right now so i'm not gonna bother calling and wasting any of his time.

[jb4g]

Where exactly are all of these glowing reviews for ddynopower coming from??? From what ive read on the 3g sites is the exact opposite....maybe Slippercream can shed some light

[XFactor]

Mitsustyle.com, a bunch of local (local relative to me) DSM owners (passed and present) as well as EVO owners.

Here is the bulk of the thread that I made on the forum:

Anyone heard of this guy?
Doug's Dynopower? Doug's Dynopower

He claims to make a 4G Eclipse GT/GS turbo kit. Anyone able to comment on quality of his passed work? His catalog includes DSMs, the 3rd gen eclipse, and EVO 8s.

Someone on a forum said some guys from Buschar said he was very knowledgeable, but thats second hand.

That guy is an OG. He has been around since the 90's. Back in the day of Extreme Motorsports and Buschars hayday. He did some good stuff back then, but haven't heard about him in a long time.

Re: Anyone heard of this guy?

Yeah, he has been around forever. He has a good rep so he doesn't really advertise or want to be one of the big places. He is on NABR still and I bought my FMIC kit that I am still running from him eons ago (7 years?). He was the first I knew of to do a twin turbo DSM.

You can read more about him on the 3G forums as well. I've only heard good stuff about him.

I kind of think the fact he's been around a long time says a lot for reputation. I'm not trying to advertise for this guy saying "run out and buy his kit it is our first big solution!" -- but I do think it should be looked into by anyone seriously considering a turbo option right now.

At least call him and get some specs. As I said, i'm not really in the market for one right now, considering it eventually, but not for a good 12+ months.

[XFactor]

In case it's confusing reading that copy/paste that last comment under the line I tried to make is an added comment by me.

[jb4g]

well, that does seem to be some kind words....im assuming most of those guys are 1g/2g owners?

[XFactor]

Most of the guys on the forum have owned a DSM at some point, so i'm honestly assuming, but the core posters there are all current or passed DSM guys, some moved on to EVOs, some went to other brands, I would say it's safe to assume they have all worked on a DSM.

There were 2 more replies since I last posted that copy/paste also.

But yeah I mean like I said, it's at least worth talking to him and getting some info. I'll let someone else do the research and be the first to install the kit though. I don't like being the first person to do things unless it would be a local shop where I can watch the progress and ask a lot of questions.

[jb4g]

well ill be interested to see what he says....as a group we will know right away if he knows the 4g and its issues going FI or is just talking out of his ass. I sent him an email over a year ago when someone posted him up on the .com site...i never heard back from him, and the info on the site has never been changed from what you see.

[XFactor]

Ooooh really?

Hmm.. well that changes my perspective a bit. Maybe he just doesn't check his email much? Either way, if someone calls him and gets a hold of him pass on whatever info you get.

"DDynopower@aol.com" to me
show details 7:41 pm (1 minute ago)

We been working on the 4cy kit lately. Have had it running a year now but have been getting it ready to make in numbers.
The V-6 kit will be awhile yet. Its been running well over a year but as far as selling the kits, still working on the ECU.

[Tech_Greek]

Sounds like RRE's experience with their boosted 4G.

Wonder why RPW had no problems with the Galant 380! We have the same ECU or relatively close to the 380's and the Eclipse GT's is the same as the Galant (minus the MIVEC crap).

[360jeepboy]

I wonder if anybody has tried the AEM FIC for fuel control on there turbo cars?

[Tech_Greek]

I don't think fuel control is the issue, I think the ECU is going into limp home.

[sullysdetailing]

f the ecu stand alone system

[Tech_Greek]

Exactly

[eclipsercr2006]

i personally talked to Doug when i still had my 3g and he seemed to know what he was talking about and seemed to have alot more plans for the 4g than he did the 3g but this was all 2yrs ago so.

[x0xaprildawn]

who ever told you that you had to have a cast iron block to boost needs slapped... lol if that was the case they wouldnt be boostin LS1 LS2 LS7 blocks and pushing the 1k mark... Now dont get me wrong an iron block will hold more but at the end of the day you can boost anything with supporting mods such as fuel pistons rods and what not.... plus like they said you have a aluminum head set on an iron block.

[x0xaprildawn]

well um that was my future hubby posting under the wrong name...but anyway....lol...

[horse-eater]

8 psi is the most they have pushed it to. I think that it can handle more.

Failure on boost comes from 2 major things in my opinion.

1) Fuel

2) Overpressure of the cylinders.

number 1 is easy. the only way to find number 2 is keep pushing it until it happens. BUT with that being said. 12psi on a 2.0L motor is different than 12psi on a 3.8L... I was educated about this by my cobalt buddy that still posts here and on the other board occasionally.

We have a higher compression ration to begin with. 10.5:1 as everyone knows. So typically, when doing your turbo build on paper, you would set a target compression goal as well as pick your turbo or supercharger based on your HP goal and how many CFM's it flows. Which is okay.

But what many people don't typically take into account is that the bigger the motor, the less change in real compression ratio there is. So theoretically, if you have 2 exact same engines but one is 1L and the other is 2L, both starting at a 10:1 CR, then add 6psi to each one. The 2L should have a lower 'real compression ratio'.

There is also the factor that PSI is the same as CFM's when people talk about airflow.... NOT TRUE, you can have a turbo or supercharger that boosts insanly high, but not flow alot of air. And vice versa. SO that is important when picking out what model you want to use in your build.

Now don't quote me on this, because this is merely the way I interperated the information that was presented to me by someone else who interperated it from someone else, and so on.

But I hope this helps someone somewhere a little.

[CBT83]

sounds good to me
