-30psi on pump 93? WTF?redrkt said:He has a smim, it's the turbo that's falling off up top. I think it was done at ~28-30 psi.
Being that i'm FWD, 350'ish is plenty on street tires.anconover said:That is not your standard off the shelf 50trim BTW.....
So dont expect anywhere near those numbers on a standard 50trim.
Most ppl honestly should not plan to see over 375whp on pump gas on a 50trim, even with cams etc.
anconover said:How can i not say it? Good for your friend and all. But out of all the 50trim owners, which is alot since its the new fad, how many do you think are making over 375whp on pump? Sure you hear of a few, but thats only a TINY percentage of those who own one.
So i can clearly say. MOST shouldnt expect to see over 375whp. An incredible amount of people have little to no tuning knowledge and expect to learn it quick once they build theyre setup, and it never runs like it should.

[voice from mxc] Right you are ken[/voice from mxc]redrkt said:I'd agree, you can have all the parts in the world, but without knowledge to tune you aren't going to be able to get the most out of your setup. Often you will see people with big turbo setups not even running as fast as a well tuned 16g car.
However, i think people should expect to see what the turbo is capable of if they decide to buy it. The 50 trim turbo is very capable of making 400whp on pump gas and up to 500whp on race gas with cams and the rest of supporting mods even on a stock engine, for the knowledgeable people out there. If the person lacks the knowledge, they should pay someone to tune for them.
My thoughts too. Whats the point of it if you can only adjust it to one enviroment? I would rather pay someone to teach me or just practice on the stock turbo.Violater101 said:Very well said. And the problem with not being able to tune is your car can be dead on at the dyno, then you go to the track and it's a totally different animal which require adjustments.
BGGSTin said:Quick question guys, I don't have a 50 but a Evo 3 but I have a HP question.
Okay, lets say you had somwhere around 320 horsepower and your boost was increased by 8 psi from what it's to be around 320. Do you guys have any guesses as to where I would be setting HP wise then?

daren_p said:Well they usually figure 1 psi is equal to about 10 hp, so that should be about 80 more hp. But thats not always the case, if you make 320 hp on the evoIII, you would probably be running atleast 20 psi to start with, so you have a bunch of other things to deal with, such as effiency range of the turbo, knock, blowing your stock motor apart, etc.
I'll try to make a pull and post it on how bad the knock is when its creeping, but I never really intend on it going that high, it just happens; for some odd reason

mildly ported my old evo would only creep to ~24 psi. extensive porting held her 20 to redline vertGST said:friend of mine on here made 380 fwhp on pump with 22 psi i think on an agp 50 trim. stock internals, cams, etc. It's all in teh tuning.
He ran a 13.2 with 18" wheels and bobo tires
