GTI VS SR20 VS TT RX7 + video

[Jehu]

:jerkit: slow 4 an apr APR stage 3? well lets see it was tunned & installed by APR... and no you can not get 320 whp daily driving a stg3 iam already at 25psi, a stg 3+ kit will make 320-335.

atp better then apr? nuff said

25psi and less than 320? Is this typical? No disrespect as I'm not familiar with GTI's but that seems like a lot of boost for the HP.

My experience is w/ hondas but even the bastard Honda motor (B20a/B21a) would make 300hp on 15-17psi. Is this typical (the difference of Honda's vs VW's being boosted)? I have a friend with an H22 (very much built though) that's getting 420 w/ only 17psi. W/ 25psi, I'd almost expect upwards of 600...

If this is typical, what is the difference (of course, this might not be the post to discuss)?

yea vw is a little crazy when it comes to boost... a chipped 1.8t will hold about 19psi on the stock turbo. about 190-210whp max at 19psi yea BT setup are from the 24-25 range. ppl always freak out when i say it holds 25psi

Oh god! That bad??

Yeah I'm guessing you put out like 230-240.

Stock SR20 with fmic and exhaust can put that down to the wheels.

Halfbaked sentra dyno'd 202 at stock boost witht those mods.

My car about the same, like 205 tq in stock trim.

Even though these are 2.0 liters 7 pounds vs 19 pounds is a big difference.

Yeah but 25psi and only 250ish?

So 19psi and only 190-210? H22's do that w/ a few bolt ons so I guess boosting them, you just start off at a higher hp to begin with. Maybe some port and polishing would help the flow? What compression are you at?

19psi on my motor would be crazy...even w/ 9:1 compression (currently 10:1). I could probably put 7psi and easily get 300+ on my current setup (after I change my valve seals though!...and I already have turbo cams, port and polish, and forged rods)

GTI stock turbo is very very very small...KO3
