300HP+

BTW, I think it should be clear that my previous post was directed at rave, not marty. Just thought I'd say something, since I just now realized he slipped one in before I saw it.

No problem, Jon. I figured you weren't talking to me.

Just to add to my earlier comments, I don't have a problem with making 300+ HP with boost. I just don't think you can make 300HP NA with one of these engine without lots of money, and making it unstreetable. Once boost enters the equation, 300 is easy. Curtis' current best dragstrip times are not really a good example of the true potential of these engines, since he is limiting power due to traction reasons. I think he has the boost limited to 12 psi, and he is still making killer power. His engine is capable of a lot more power than he is currently making, but he just can't use it. Just imagine that engine in a Fiero with the boost turned up to 25psi. I bet 500HP is doable with his setup.

Here's another question relating to all of this. At what point will I need to really mess with my computer? If I were to run a turbo kit from http://www.exploitedracing.com, could I put on a Stage 0 or Stage 1 and still keep the stock computer? How much additional power will it compensate for without throwing a fuss?

I belive that 300+ hp is achievable on a 3x00 engine with forced induction. On my 95 MC with a 3100 I ran 134hp/164tq at the wheels without a turbo. After a stage 1 setup running only 4 psi I went to 171hp/218tq at the wheels

With drive train loss thats about 220hp and 280tq at the crank. Not bad for only 4psi. If coupled with a trans that can take the boost and other supporting modifcations I think its very possible to get 300 or more our of these engines.

As a matter of fact I will be going for it again with my "bad for preformance applications" 3400 I swapped in after I lost the 3100 to an Oil leak.

With a proper build up and a trans to match I am hoping to top 350hp but I will have to wait till next summer, my wallet is thin these days.

3100 info

maybe off topic... but anyway.. im new to the 60' club.. mostly v8s ( fords and chevys) but ill be getting a 94 pontiac grand am se 2dr soon, 3.1L w/ bloan head gaskets. 2 questions... what is the stock hp for this motor??? and will a 3800 supercharger fit on a 3100??/ or would be beter to get aftermarket?? Would be better to try to find a complete 3800 eng / trans and bolt that in?? I too am looking for a little more hp since the heads have to come off...

[ikessky]

Suggestion: Never talk about the 3800 here.

Stock hp is something like 140-155. A stock 3800 S/C will not fit without major modifications.

Back to my questions now...........

[jimraelee]

not talking abou t3800???

why not talk of the 3800??? is that a 4 letter word inhere???

[ikessky]

The 3800's are 90 degree V6 engines. This is a 60 degree ONLY board. So to answer your question, yes, 3800 is a four letter word here.

hehe sorry, I was running 4psi with NO MODIFACTIONS, stock internals, stock iginition (just NGK plugs and wires), stock computer, stock fuel system. Theroecticlly the engines internals can safely take about 8psi but I would reccomend an adjustable FPR and iginition to go that far.

Also note my car is ODB1 which as I understand it is a little more tolerant to stuff like this without tuning.

The one problem I had was when stepping on the gas to hard sometime the trans would either die-engauge or not shift out of second. I think the extra power was tricking the computer there.

My next kit will be on a built engine with most likely either a modified ECM or a custom computer, still not sure.

like i said get ahold of me if you want to
i get a little anoyed with a whole site full of people barking at me cause i dont conform and agree to everything on the site
btw why isnt there anything about the 3.5 DOHC motor on the site
that jsut goes to show you that the site isnt necessarily the bible

[SappySE107]

The 3.5 isn't a 60V6. Just goes to show you don't know what you are talking about. Conform...its FACTS! WTF, do you go to schools and tell people in math class not to conform to the multiplication tables? Same damn thing. If you wanna prove yourself, go for it.

We dont have the engines not sold in the US on the site, like the 2.5 and 3.0. If someone came to the site and we had more interest, I could add it.

What he said!

I figured the links to GM Powertrain would have convinced you rave, but obviously GM Powertrain is wrong as well, and you are right. I guess we need to start going to you when it comes to info about these engines, cause obviously you know more than the engineers that design and build these things!

[Guest]

I'm going to have to change my name now, I don't want people to confuse rave and myself as the same person, too many letters in the same order.

rave: word of advice, if you want to "prove" yourself, say it here, with links and other verifiable info, don't try and persuade others to change what they think without that, since well, you wont. I know for me, I don't just look at numbers written on a piece of paper or my screen, but actual measurements from actual parts.

I'm still wondering about the ".050"" timing thing, still can't make head or tale of it

[TheProfessor]

ok i have a 3.1 crank right here someone with a 3100 crank measure yours and we will compare .050 timing wall that is the lift measurment at which the cam specs are taken and why does the gm service manual for the olds intrigue say that the 3.5 DOHC is a 60 degree if it is not
