    STi vs. 944 turbo

    I hung around a nice STi last night, on I 85 south. Had the plate "FORCED4". Very cool car, and cool driver too.

    Anyway, we just played around. Got on it together 4 times. He did a stint w/me just watching once as well. We got on it on his mark pretty much every time. I had no problem keeping up, but it was pretty close, one of the closest I've had. I don't know how fast these cars are but I'm about even w/a 6 speed C5.

    Anyway, it was very nice. Anybody have accurate specs for these cars (I would appreciate the upper speed range #s like 60-100etc.). It seemed like he also had better response/less lag compared to my car. Appeared to be bone stock.

    welcome to the club.

    if you don't see the response you're looking for, feel free to double post (this time. ) in the STi forum. you'll get better response in there.

    Hi Ahmet, I noticed you lived in the same town as me.

    Any mods to the 944?

    Thanks for the welcome dark, I assume you're a moderator here?

    Ya, I've got this and that on my car. Currently running 15psi (the #s I have on the link are w/the car tuned @19psi). Follow the link in my sig for some specifics. It does 70-100 in about 4.2 secs as is, vs. the ~3.6ish @19psi. A couple of things have been changed since then, but nothing major. I'm thinking about going to a bigger garret, bigger injectors, etc. BTW, I wouldn't mind checking out your car sometime. I've been thinking about getting a WRX, but it's still in the air. Do you have any mods in yours?

    edit- doh, I see your sig now... So, just how big is that turbo?

    3.4 second 70-100mph!

    Well, anyone know how a TXS Stage IV Rex or an STi does in that?

    That just seems crazy...then again I drive a Honduh.

    Well, yesterday I timed myself 70-100 several times. In 3rd I did a #of runs ranging between 4.2 and 4.6 @15psi w/luggage and about a full tank. The 3.4 sec run is on a cooler day w/19psi. I've gone through a couple of turbos doing that in just a few 1000 miles, so I'm keeping the current kkk @15psi until I go to a larger compressor that can move the same CFM w/less rpm shaft speed, or go to a ball bearing turbo. Like I said that's still in the air. Judging by all this, I would think the STi would've done 70-100 in the high 4.Xs. It's not too hard to get more power out of turbocharged engines you know.

    Having said this, I raced a civic w/a JDM civic Si motor. I thought that was close, but he was somewhat dissapointed in his car. In all honesty I was just suprised that he wasn't completely wasted considering I've got a somewhat modified 2.5l turbo, and he had a 2.2(?) normally aspirated engine. That was also @15psi. Two cars weighed similar I would think. I'm around 2800#s wet.

    Don't let this make me sound like a street racer though, I'll mess around every now and then on the highway, conditions permitting but I like doing OT events much better, and don't condone "street racing".

    Nice car! I've always loved the look of the 944's. Several years ago Car and Driver published an article on what they thought were the 10 most beautiful cars of all time. Along with cars like the E-Type and the GT40 was the 944 (I think).

    I don't know the exact time because I've never kept the gear low and punched 70-100 mph but in 5th it's just a few seconds when you put it to the floor...unfortunately, I have to do so frequently to pass people. This is for the STi, of course.

    Quite a few of us 944 t owners time 70-100 as well as 60-90 and 60-100. Can you hit 100 in 3rd? I've never tried 5th, but I would assume it'd take around 8 secs or even more, too tall (remember 4th tops out around 140 indicated on a 944 t).

    Anyway, the procedure for the 70-100 test is roll @60 in gear. Floor it, start timer @70, stop @100. This eliminates variables like traction, tires used, driver ability (shifting/launching), etc. and gives good, real world #s. Aside from all that, it's not hard on the car. Ofcourse w/the awesome launch capability of an STi/WRX, you may not want to compare just these #s. FYI I can do 5 secs to 60 in my car on street tires, but it seems like anything that has over 250 hp and awd it takes me till the top of 2nd to pass them (2nd tops out @68mph). Anyway, I'd love to compare #s if you can time your car, please indicate which gear you were in, if you do so. While we're at it low 13s in the quarter w/110ish trap speed.

    edit: renichms, thanks. I really love the look of the 944s (specially the turbo/S2 body type). It does seem to polorize opinion sharply however. A good friend of mine owns a 3rd gen prelude and thinks that 944s look "ugly and dated".

    3rd definitely won't hit 100 mph. 4th might but I can't remember because the only controlled high speed run I've done recently was to 140 mph. I do know that 5th topped out before I got to that point...I'll test sometime soon to at least get rough #s.

    I got a friend here with a non-turbo 944 and this weekend, we should be making a fun run on some empty back roads here (on film). He knows someone with a turbo 944 who'll run with us sometime soon...

    It's not as big as people think. I make 15psi by 3200 and hit 24psi by 3800. WRX's have a 7000 rpm limit too so that helps.
    I don't get off work until 9:00 tonight, but if youre free maybe we can get together and check out each others rides. I'm running 93 octane now so I'm only running 19psi as opposed to 24 on 112 octane.

    Let's do that, I'm sending you a pm w/my phone #. Just drop me a call and we'll meet somewhere. Oh, and I run 15psi on 89 octane!

    BTW, I tried 19psi on 89 octane but got too much ignition retard. Hopefully a more efficient turbo will allow more boost on 93 oct.

    Try running some 100 octane from the BP on the corner of Kildaire and Maynard. I'm sure you'll be able to run close to 19psi then. I throw a gallon of 100 octane in when I fill up with 93 to act as a buffer. It works great.

    I wouldn't pay $5/gallon for gas unless I really needed it. I don't knock @19psi w/93 octane gas. I'm just saying the turbos don't live long... I did 19psi on 89 oct. before but it had too much ignition retard...
