Anyone hear of the 3.4dohc having 275hp originally?

[JasonZ34]

I'm still waiting for a reply. I was excited to hear of a N/A LQ1 with 225 at the wheels but now i'm depressed. So if you, Kevwood, are going to back up your claims and post mods please do so or say you aren't because No answer is an answer IMHO.

Give him time. He isn't going to be sharing a whole lot at the moment (ive been talking to him via email). I will say things sound legit but yeah, we will have results soon enough.

Just for your alls knowledge the 90 prototype was not built with the 3.2 dohc. It was built with a stock 2.8 engine that came in the fiero and was later redone with the 3.2.

0wned. I think I banned him again anyway so he may not reply:P

So it looks as if 275 is attainable and more......Yeah Kenwood.

If we only had the cams and headers.

I might be out of my leauge here but I found headers for 96-97's

Also how do you get Kevwood's link to work?

It wont cause we just changed our software setup.

I copied the t= part and put it in where its normally p= now

Had a conversation with an engineer who had some insight as to how this engine may have had more power in testing and prototype then it does in actual production...

He's worked as an engineer working on aftermarket products (mostly headers) and one of the things that GM may have done while testing this engine is use headers on the engine test stand, along with a tunable intake (meaning they can change the runner lengths without much effort) to get the max horsepower/tq along with the the ease of changing cam timing this too can help with some of the power gains/losses ... I think we can see some of this in the the production engines with the fact that the cam gears are not key'd for any one location and have a full 360* of adjustability.

To me, this makes sense, if you were to have tuned headers to increase the scavenging effect, and be able to tune the intake manifold to match those headers, and then set the cams and tune the program for a given RPM range, you could get GOBS of power, do I think they did this, well yeah, GM, Ford, Mopar, all these companies start out making as much power out of engines as they can, and they dial 'em back from there for both reliability and cost of engineering all the parts to fit 'round it, such as the transmissions, engine cradle, engine mounts, axels, bearings, and so much more.

Remember, when you start adding power, you'll break more then just your transmission, you'll break all sorts of things, now imagine if you had to re-engineer all these other things to make it work right ... Cost would tower over projected sales, so a balance has to be made.

do I think we can get these kinds of numbers (on an engine dyno) sure, why couldn't we. There's a combined knowledge of automobiles on this site, and really, we're all here to help one an other out -

Damn, that was pretty much the best way to some the title of this thread and this board up.
