Default CTS-V vs 21psi STI

My cts-v has intake, catback, and a mild cam.

he said he had full bolt ons and 21 psi on the stock turbo.

It was qwker then i expected.

First gear roll at about 35 were back and fourth 1st ,2nd, and 3rd gear , then 4th gear I started to pull away and held it..

Second race race a 50 roll and the sti got a jump on me from the honk and I was at his rear bumper, then finaly again as soon as I hit 4th gear i realed him in and was able to take the lead.

Was one of the qwkest stock turbo STi's ive raced (he said it was stock i took his word )

srry bors no vid this time, left my camera at home

Any one know what type of power a STI is puttin down with full bolt ons and 21psi ?

Nice kill.
All I know about the STI's is that they boost 14 psi stock and I'm pretty sure 21 psi is pushing it for the stock turbo.

Yeah 21 is pretty much the max of the stock turbo unless it was an 08 new body style with their larger turbo. Assuming he is tuned or has a mapped ECU with supporting bolt ons he should be between 300-320awhp. Fastest stock turbo STi I've seen was around 11.7 @ 115 w/ meth injection and pretty much all bolt ons, but he's realistically got a low 12 second car @ 110 or so.

Good kill on a quick car. The stock turbo and gearing sucks for top end so it would be interesting to see you guys go from a dig on video.

From a dig I dont think I would stand a chance to be honest if he knew how to launch it....

The thing moved ..

he could have a stock turbo but have a tons of stuff done to it and might be in the upper 300awhp range, but their gearing wasnt that good in the older ones so they suffered a bit frm roll races

he'd have to have a REALLY aggressive tune to be in the upper 300's on a stock turbo.

usually they are around the low 300's on a mustang with boltons at that psi they weigh almost as much as an fbody lol

Wow, i would think more then low 300s, but then agian that sounds realistic compared to bench racing " I prolly dyno around 450" noise some guys talk on the st.


also as far as weight goes my CTS-V is like a f-body with 4 ppl in it, so The v did well IMO..

I almost bought a STi becuase its fast and CT weather sucks(snow), but a few of my buddies have them and i just didnt want the same thing ...
The cadi is a **** load of fun to drive, and rides nice and smooth... Only downside is all winter it sits in the garage....

Nice kill, man. I haven't seen your CTS-V around but it would be fun to get a friendly run in if we bump into each other this Fall (looking to have my car back on the road in the next few weeks after a trans rebuild).

I'm not sure if they are the same motor, but I ran a guy a few times with an Evo 8, cams/full bolt-ons and meth on the stock turbo running about 28psi. He made around 370 at first if I recall. First runs were close when I had a passenger and shifting issue, then I sorted out my issues and showed up solo while he got retuned to about 385 and I walked him pretty good. We were both surprised because those are light cars.

I'll take your word for it! I know very little about both. I don't know where I got the idea that they had similar motors but it's always good to learn and I never bothered looking it up.

BTW, I know someone who would be a good run for you here in CT. 02 Z28 with a cam and 100 shot. Should be putting down similar hp as you if you're interested. Just finishing a clutch breakin today and tomorrow and I know he's planning on going up to the pike this weekend to test out the new clutch.

How much does your car weigh? I'm definitly down for a roll or a dig when I pop the tranny back in but I don't think the dig will go too well unless you've got some very sticky tires and a strong clutch. Regardless, I love just running for fun and I'm in love with CTS-Vs, so I'm good for it.
