Good luck, I want a dyno sheet once it's all finished!

The Supra owner is a really good friend of ours. I messed around with him yesterday but he's not setup to be messing around with bikes yet. He was on his low boost setting, he didn't brake boost, and he was having traction issues from 40 mph in second gear as usual because he runs 19" wheels and no drag radials. I was in first from 40 and jumped out quite a few car lengths from what I could tell before he stopped my pull. We both shut down fairly early because the G8 and Shelby were up ahead finishing their run and coming up fast, but I think I took it to about 115-120 or so. The passenger in the Supra said he thinks they were coming back on me but they were far enough back that it didn't matter (and the Supra owner didn't sound so sure that they were coming back on me yet). I couldn't tell, I just know they were still pretty far back there.

Like I said, the Supra owner is a really good friend of ours so we were just messing around and we all know the car has a few things it needs done before we really get some legit races in. If he can brake boost and solve his traction issues on the current power setting, it should be a decent race with me jumping out pretty good down low and then him coming back in triple digits. It will just be a question of how long it takes him to catch me and if we have to go into super speeds for that to happen. I typically shut down around 125-130 (top of fourth) because this bike just doesn't have much after that, but he and I talked about it and we want to do a bunch of runs where we have set start and end speeds to see if can catch me by those certain speeds. For example, 40-120, 40-130, 40-140, 60-120, etc.

From 60-70 where I start in second, he's gonna keep it even and then start walking hard in triple digits most likely, but from 40 or so I should take him off the hit and then see how long it takes him to catch up once we really get crankin. We'll definitely get some videos for those runs. And once he ups the boost, I won't have much for him on a stock 600.

The supra is a 74mm turbo making 645whp and 502rtq at 21 lbs. He has one more tune making closer to 700whp, I wont put his exact #s on here.

I drove him to pick the car up and had my car tuned at the same shop. Along with PSM I am very close with the owner, we cruise together on a weekly basis.

I was the passenger in the supra last night and when PSM took off we got into boost but PSM had already jumped out a good 5-6 cars. By the top of third it appeared we had stopped the pull, but I doubt we would have caught him in 4th, would have taken more road, and at least another 40-50mph. Powershifting on the bikes makes a HUGE difference, the bike definately pulls like a raped ape from 40mph.

Once the 8 rib is on I want to run the supra/bike, that should be a good race for video

LOL that fox was horribly slow for his mods. Horrible. Maybe he didnt install the heads right or needs a rebuild or something....

My h/c/i fox with way worse parts(gt40p heads, explorer intake, full interior with a/c) would destroy my g8 when it was stock. I think it would still beat it now although it might be close from a 40 roll.

I got a kick out of him talking **** saying he would beat u and then being slow thou! haha! Time to mod that g8!

That should be very interesting once he does that. It gets old seeing Supras making big power but cant even get traction until 70+ because they wont throw on a good set of wheels/tires.

I think you are pretty much dead on. I dont see him pulling you while you are in first. It is VERY hard for a car to pull a bike (from a roll) while the bike is in first. To have the power to do that with a car, its hard to get it to hook right. I think any low roll, you will jump out and hold him off until around 120 where hell come creeping by. A 70-150ish would definitely be something good for him.

Any plans to change sprockets on your bike one day?

No problem, we'll hang out next time!

I would also like to get a couple races in against the Supra. If nothing else, it'll sound cool flying by me

As a fox body owner I am very disappointed in that Fox. Should be running way faster than that

In my experience, fox body GT's with just a H/C 302 are not real quick, because of them being on the heavy side. At least by me, every one I've seen hasn't impressed me much. I would say it's prob a high 12 car at best. Plus, the kid just got the heads on it that night and it wasn't tuned for them. I'm sure with the right tune he'd be a bit quicker.

No plans to mod it at all, actually. It's bone stock (minus the fender eliminator) and I want to get a 10.9 at 130 out of it at the track as it sits, no strapping or anything. I'm not sure I'll be able to but considering my weight and the fact that a few people have done it, that's the goal. By the time I can do that, I have a feeling I'll be ready to upgrade to something new, although I do love messing around on the 600 because I can go WOT and powershift every gear without having to feather it or flipping it.

And if we do a 70mph start in second for me, I have a feeling it will stay close until triple digits, then he'll walk away, especially once we hit 115-120, if not sooner.

I'm also not a fan of the old 5.0 against anything newer. Sure they were fast back inthe day, but back in the day anything running low 13's/high 12's on stock longblock was considered fast. And low 13's/high 12's is what your average heads/cam/headers/intake/ gears 5.0 mustang runs. - with most in the 13 second range.

I was under the understanding that "tuning" a fox body was turning the distributor and changing the timing. I didnt think there was much else to it then that. They dont tune like the newer cars its basically timing and fuel pressure only. I could be wrong but im pretty sure thats about it.

Back in the day low 12s was the norm for a heads/camed fox on drs. And that was with a mild cam(Motorsport rebadged Crane cams) and okay heads....eeeck. I used to smash up bolt on LS1s with mine from LS1.com and z28.com. Don't see many on the street much anymore....

Yeah, they can definitely be made to run real fast with the right heads and cam backed by the right supporting mods and tune. That said, the majority you see these days aren't max effort builds, just basic bolt-ons with a whatever heads and cam the owner picked out of the catalog. I've run another guy I know who has a very basic heads and cam on his LX and isn't known for beating on his cars and I was dead even with that car as well. He estimates it to be in the 270 rwhp range.

To get max power you do have to adjust your A/F on them. They sell the matched MAF and fuel injector kits but thats kind of a handicap for a proffesional tune. You'll get it running pretty decent with those kits, but if you want the most power you can get you really do want to actually have it put on a dyno and make fuel press and timing adjustments as neccesary....thats kind of what I meant by tuning....not so much plugging in and re-flashing a computer. They are fun cars though and I love how small they feel when your in them. Almost like a honda civic with a V8 and RWD haha. Hope no one takes that the wrong way!

Were up in the Northern part of CT around Hartford. We ussually hang out around the Newington area (Berlin Turnpike). I want to guess it's about 45 mins from New Haven, but I could be wrong.

Looks like you're right on the money. If I'm ever up that way for the weekend and there's something going down, I might have to get ahold of you fellows. It looks like a damn good time. Got to get some sort of tune first though (shifting issues after stall).

Def man! The more the merrier. I'm sure we could find someone that was equally matched for you to have some fun with. It's a good time!
