S5 TurboII 13.75 @ 104 - how?
I took the TurboII to Lapeer dragway today (about 65 degrees outside by the way), and ran quite a few times.. ran a few sub-14 times, best was 13.7 @ 104. I was shocked that I ran that fast.. I was hoping to run like 13.99 or something (previous best was 14.1 @ 100, before I put on the cone filter).
Basically all I've got is a custom turbo-back single exhaust straight through to a crappy "silencer" (can't even call it a muffler". And also a cone filter (no cold air box). Also I should note, the DSV is acting up, so it runs to about 6 lbs and stays there. SO.. basically I ran 13.7 @ 104 on 6 lbs boost. That's not too bad. Oh, and I've pulled out some miscellaneous weight stuff (nothing that should get me THAT low though..) I've pulled: Spare tire Sound "carpeting" from back Rear trunk separator thing (that piece that makes it as if you have a real "trunk") Stock exhaust (pretty heavy) to the custom single exhaust (not AS heavy). All that though, I'm really curious now as to what I'm putting to the ground. |
Oh and Jim (Raptor13x) ran like 15.8 in his '85 12A with no performance mods (except his exhaust is custom (CRAPPY) from the thermal reactor type thingey back to a pretty quiet muffler).
|
Thats a GREAT time!
|
I think you're just a good driver
|
ran a 13.8@104 ;)

heh great time |
hm.. I need to gank off the air pump and I'd love to ditch the stock power steering rack, and put in an electric one or something..
|
With 104 traps you could probably get below 13.5 with a hard launch.
|
congrats..
that homebrewed turbo-back exhaust is prob. most of it. Probably added a good 50HP if not more I would reccomend getting an SAFC and/or injectors Very impressive times man! |
yeah but it's only running 6 lbs boost.. that SHOULDN'T cause +50hp over stock.. something is WAY goofy in this car I think.. I'm gonna take it to the dyno I think, and also weigh it.

Well, isn't the engine in your car a J-Spec? Perhaps it's ported out or has some tricks done to the inside.

very nice!
i ran 13.7 @ 100 MPH with my old TII @ 7psi with dp,mp,tid, act race clutch :) |
vosko,
I remember an old thread when you had the tII and you pulled a sub 2.0 60' time on one run. What tires were you on? I remember it was a street tire of some sort... |
i did 1.92 60 FT on kumho ecta supra 712's on stock rims . i launch mad quick yo! :)
i am on the lookout for another 89-91 TII... |
what are common 60ft times for modded TII's?
|
2.00 is excellent for any car on street tires.....
|
isint stock times like 14.9 1/4. How in the hell did you cut a whole second off with just a exaust and intake?? Damn makes me wonder what i can pull. What is your car? s4? s5? stock engine? or Jspec as mentioned beofre
|
he said it was an s5 i want to know what i will run
|
Damn! those damn s5's i bet thats why too, i dont think us s4 ppl can get that low with such basic mods, but im sure with the correct driver itll be real close
|

Hey i wasent serious, i still cant think of a good reason to why its that low, but hey im thrilled either way...

I bet he has a port job

Specs:
- White 1990 TurboII - S5 J-spec engine imported from a guy in Canada ($1100 for engine and tranny SHIPPED.. good deal) - Lightened, I'd guess maybe 100 lbs from stock, due to removal of stock exhaust (heavy) and put on the single turbo-back. - Removed A/C & all stuff associated with it - Removed sound deadening foam (not the hard stuff ON the metal, but the foam) from rear. - Removed rear windshield wiper sprayer (wiper goes soon, doesn't work) - Cone Filter - That aformentioned ghetto 2.5" exhaust - As far as I know it's a stock clutch, and I know it's stock flywheel - Kumho Ecsta Supra 712's 225/50/R16 all around - That's really about it.. I don't think the TB mod has been done or anything.. and like I said it runs to 6 lbs and really doesn't creep over that (the DSV is acting up, that's why it doesn't go to 8.. wonder what I'd run then if I had a MBC and it went up to 8 right away :) ) And it also bleeds off as I approach redline, going down to about 3 psi (I think) or so near redline. New fuel filter & spark plugs, I dunno.. and Mobil 1 oil filter, heck I dunno.. and about a half a tank of gas.. 65 degree day. By the way, the 60' times on those two 13.7 runs were like 2.091 and 2.065. This track has a real sticky starting line. A stock Z28 (stick I believe) ran like 13.5 there. |
All right.. who's around the Detroit area? I know Chris Sanders is downriver of here, I know JimmyV13 is arond here too, along with Fox4Life and FreedS4.. but I don't know who of them can for sure identify a ported engine just by hearing it run.
Wait a minute.. Andy at Mitch's Auto can do it.. maybe I'll take it to him tomorrow. Yeah... THAT'S the ticket. I've got a caliper I need to take back to him for a core return anyhow. |
i have an idea. get some video of it ;)

1.93 on kuhmos is pretty hardcore. How did you launch it?
|
1.929 ;)
did monster burnout. revved to 8000 rpm and dumped the clutch lol |
what time do ya reckon id run with my mods and my car is running a bit better than when i got dynoed the dude did a shit job im just waiting till my FMIC is in before i get it tuned
|
high 12's to mid 13's....
|

Yea I can't dump my clutch out at anything over 3500 or I get mad wheel spin all the way thorugh the 330ft adn my car just has a cone filter and is N/A !
I pulled a 2.06 60 ft on one of my runs at a local streetrace type venew at the track . I missed 3rd though becuase my shifter bushings are shot to hell . Some type of 215/60/14 tires . |

I am in the Detroit area, and had a street ported NA for a while.
Not that I think Vosko is a lier but, I would think launching that high in a modded t2 would just spin the shit out of the tires. |
i spun the tires but i got it to hook. i experimented alot with that car. i drag raced atleast twice a week. sometimes i even went racing three times a week!!! it went from dead and bone stock to dead and ran 13's in a matter of months ;)
|
this is from englishtown after i put on the apexi n1 catback and its last drag race since the engine broke on that run :(
http://www.vosko.net/media/dragracing/voskot2-1.wmv |
15.3?
|
WOOPS
this one sorry. that was the first time i drag raced it http://www.vosko.net/media/dragracing/t2blowup.wmv this is the right one lol |
I think it ran it because you got Nawwwssssssssss from TFATF!!!
Double Clutchin and not granny shiftin! yeah!!!!! |
What elevation was the track? A Cool day so that helped. Those 60' times were pretty good so that helped. I'd say a combination of cool air a sticky track and air density that day.
Good times!!! |
hmm..
Your jspec is either streetported or your boost gauge is off.
I know good driver has alot to do with it. But a stock s5 motor/turbo with a full exhaust and cone fitler only running 6psi would NEVER EVER run 13.7 @ 104. The full exhuast and intake would spike you over 11-12psi with is past fuel cut. A stock s5 runs 15.0 flats and stock it pulls more boost that 6psi. My best guess is a port or maybe your boost gauge is wrong. I bet with a full exhaust and intake you could hit those times, just not @ 6psi. I ran 14.5 with a dp, md, stock catback and a intake with a slipping clutch. I would've been into the 13's with just a good clutch, with a catback , I would of probably ran the same times ...around a 13.7 @ 10x at any rate, kick ass times though....!!!! |

I'm pretty sure the boost gauge is right on, because it boosts up to exactly 5.5 and sits there, and maybe creeps to 6 psi once in a while. And if I was going over 8.whatever, it would have hit fuel cut before I put the FCD on, and it never did hit fuel cut. I dunno, I'm gonna get it dynoed I think. |
you have nothing to prove you have timeslips. i just happened to have video of my last run the car ever made lol
