12.8 @ Lots of MPH

[DSMu4ia]

My turd of a FWD went 12.8 @ 123mph a few weeks ago, on 23-24psi of boost, 110octane, street tires, etc. This is on a 2g/DSMlink/6bolt/60-1 Garrett/EVERYTHING else.. DSMlink is flowing 53lbs/min...about as much as I can push it right now until I figure what to do with my 2g MAS...debating on hacking/clamping it, GM MAF, AEM, etc.

Before anyone comments on my driving, the car is setup for the street not the track. I have very tall tires to hook up on the street and didn't think they'd do this poorly on the track.

They are 245-45-17 Falken Azenis and ALMOST hook this power in 2nd gear. I have a Phantom Grip LSD that is dying and once I put the KAAZ in, I think she'll be back to normal. They are 26.4" tall, which hurts the shift recovery. Basically I've only made like 7 passes on the new setup, all of which are next to LOUD v8's. So I can't really hear when the tires are about to spin, or are already at redline.

Basically what happens is I bog off the line, lag, boost comes up, tires spin HARD, and I shift, knocking the car down into the 4k rpm range, well out of spool. Takes anywhere from .6 to .8 seconds to recover, and then the same thing happens again. I haven't gotten enough passes to get all aspects of the pass ironed out yet.

I have 24.5" slicks here, which should fix the traction problems, have much better gearing, and should help with the shift recovery.

So there you go, car isn't tuned, is a PITA to drive right now, but pretty fun on the street. I've been running around with 110 because its $4 a gallon, and I like the white tailpipe look.

Putting new suspension on the car (car rubs real bad due to big tires necessary for proper street traction), new brakes, and going to daily drive it until winter.

Once I figure out the air metering issue, expect some times on mid 30psi range, and C16.

I've had very good luck with the Link's maf clamping, I find that even with a well flowing motor with SMIM, cams and port work the VE sliders need to be taken down a little to lean it out once the switchover happens. I ran 11.3@125 on a 60trim in a full weight 2g GSX, we have a 56trim in that car now and hope to see 10s at the SO.

You were one of the guys I was getting ready to PM on the DSMlink boards for more clamping information, hopefully I can catch up with you at the shootout and get some more information.

The curse of FWD wheelspin

That MPH is good for low 11s, must pull real nice on the highway.


Where did you get that spark plug cover from ? been trying to hunt one of those down.

Car would do 125mph I think with just a smaller tire. With these street tires the car will do about 132-133mph in 3rd gear at 9k. I'm going to try revving higher than 9k once I get the slicks in the first two gears. Maybe 9300 or so. Just alot of little things to try without much time.

The coil on plug came from Switzer Performance.

Car beats 600's on the highway on pump gas, about 100 less horsepower. Should hang with most of the kids riding 750's around here, they only do low 120's at the track as well.

Local busa's tear me up though.

I can get you the log from my laptop at home.

A buddy of mine did 10.4@124mph in his mostly stock R1(hopefully soon to be mine ) , so it shouldn't be too hard to take out its little brother the R6 out from a higher roll ( they start falling off at 120 or so).

I have seen the higher power DSM's running the coil on plug, thanks for the heads up on that.

600's really don't put up much of a fight after 120mph, I had numerous lengths when I ran the car up to 160-170mph on pump gas.

The car wasn't built to be a drag car, just a fast street car. But, there are enough reasons why I take it to the track. I'm gonna road course the car in the fall once it gets cooler.

my wifes cousin just died on a busa car pulled out onto road he was doing 110 and flew over 400 ft.

My condolences, I lost a friend to a motorcycle accident a year ago, was going in excess of 100 in his GSXR1000.


Heres a quick picture of my future bike....

I thought you had a Supra...










JFWY....Nice MPH.

 

[pickens]

Well, I think you just indirectly proved my hypothesis. I've always stated that a fwd will not run quicker than a 12.8ish on street tires no matter how much power you are making. Very good mph though. The last half of the track probably gets the crowd going wtf!

That car has to be a hand full to drive on the street w/ all that power.

 

[Generation X]

Very nice times and mph. I would be willing to bet you would pick up more mph if it weren't for you spinning so much, even with your lsd. Maybe 3 to 4mph more with better traction. I run a FP B28 with a 75 shot and HKS cams, and I only ran 88mph in the 1/8 mile. I should be trapping in the low 90 to 92 mph range, but I spun basically all the way down the track, therefore losing mph. Some people just don't seem to understand that you can still lose mph by spinning to much down the track. I also run a BMtranny lsd as well. It helps but not as much as one would think, especially when your trying to harness 400 plus hp in a fwd. I know my car is faster than 88mph because I have walked a stock 02 ZO6 from a roll.

Nice kill pulling a Z06 from a roll...heard one with an exhaust on the highway a couple weeks ago and it was deafening when he got on it.

Cool... thanks. I bet it sounded good. I was just giving an example of what my car is capable of on the streets, as with DSMu4ia I just want a fast street car. I just chose nitrous to give me that extra umph, rather than going to a bigger turbo for now. My trap speed of 88mph in the 1/8 mile is not a good indication of what my car is capable of, even though it was just my second time ever going to a strip. Traction is a bi*** without slicks. I spin extremely bad in 1st, 2nd, and the beginning of third before I can get traction. It almost feels like I'm on ice.

He wasn't racing, sorry. A 115mph+ car doesn't lose to a 90mph car regardless of driver ability, especially from a roll.

Car will easily go low 12's on street tires, your hypothesis is wrong. I could make a street tire "change" and go low 12's simply, but my tire choice for the street wasn't the same as if I was making a street tire choice for the track.

Turbo Honda's go low 11's all day long on street tires.

What do you mean he wasn't racing? I know him. My trap speeds I'm referring to are in the 1/8 mile not the 1/4. If that's what you are thinking. Hell... if my car couldn't trap around the 114 to 117 mark in the 1/4 on spray I would be very disappointed. I could pull on stock c5's with just the FP B28 and cams, let alone a 75 shot. So with that being said I think that is enough for when I walked, eased, crept or how ever you want to put it, by my buddy's stock Z06. Anyways.... as I said earlier since this thread is about you, again very nice #'s. Those trap speeds are awesome. Your making some damn good power.

 

[gimmie11s]

FWIW, stock c5s typically make around 300-320 wheel hp in stock form.. i would hope your car with a turbo upgrade and cams could walk one....

z06's on the other rarely produce less than 380 whp. My parents own one and that car is buck wild for a stock vehicle.

to the author.. i feel your pain on airflow management on the 60-1. I would log ~2700hz on 20 psi with mine. Interestingly enough, the most i could get out of my 2G maf with the 60-1 was 123 mph also... this was also on a relatively low boost setting. i can't wait to see what the car will do with 32 psi and DSMLink.

congrats on the MPH ... what kind of boost were you running?

Here ya go buddy http://www.dynoperformance.com/ I think you need to do a little research first before typing. You are correct, I can pull a STOCK c5 off spray, and with a 75 shot I can creep by a STOCK 02 ZO6. If your still confused, I hate it for you. If you don't believe me, then that's your choice, I don't give a rats ass. Have a nice day!

 

[Slippi84]

Why would anyone doubt X. He has a upgraded turbo cams nad probably the basic free mods with tuning that alone could produce around 300hp to the wheels. and if you knew anything about nitrous on turbo cars you would know that 75 shot of nitrous is more like a 125 shot. You do the math. Compare that 425 to the zo6's 350 and compare car weight and tell me why the vetts isn't getting walked.

 

[DSMu4ia]

I thought he was talking about 1/4mph, sorry.

My car traps in the low 90mph range in the 1/8th. It's picked up as much as 34mph on the back half of the track.

My boost would peak to about 26psi, but I think that was more of a wheelspin issue in the first two gears. 3rd gear would settle down to about 22 or 23psi.

 

[pickens]

I have not seen any fwd do a low 11 on street tires (hondas included). I'd bet that the only way this could be done would require complete chassis modification. I've seen a very few, and I mean a few run a low 12 on street tires. For a dsm, the fastest guys on street tires I've seen have not broken out of the high 12s. Not even on the internet have I found a record of anything faster than a high 12 on street tires.
