D-MAN63

I ordered most of the parts already, some I have on..

1) SRT Intake
2) Blitz Catback Exhaust
3) S&S Headers
4) Precision Industries 2800 TC.
5) 3.76 Torsen LSD
6) Valve Body Upgrade
7) Tom's Y Pipe.

I was wondering can I get below 5 secs or at least hover around 5.1-5.3 consistently?

Thanks

maybe on a very good day. rmmgs4's gs400 has pretty much the same setup, and his best time was 5.2, and usually around mid 5. low 5 is not easy on these cars at all, and the sc430 is heavier than the gs400 (slightly) too.

with the power you generating with those setup (mainly it's just 4, 5 and 6 anyway), traction becomes your biggest enemy

Thanks Henry, damn I am loving those pics

With all that extra weight, it might take you 7 or 8.

You mean 5.7 or 5.8? wow with all that money spent only for a couple of ticks faster.

Guys, the mods that I listed, thats the most you can go WITHOUT FI right?

Seen GS400's with just SRT/LSD/TC run 5.2's. Once I find an LSD I guess I will know soon enough. My best w/ Gtech is 5.69 something around there. Gearing will really help as most if not all Lexus's have tall gearing. With all of the interest in the 3.76/LSD, I would think someone would have called for a Group Buy on the thing. Steve, you out there?

I agree with Henry: with ONE wheel drive, there's not much traction left for big improvements on the 0-60 dash. Still can't believe Lexus cheaped out on a limited-slip diff on a V8 car.
And for the record, I don't know where the heck Lexus pulled their 5.9 sec 0-60; the best I remember is 6.2, even with the magazine's abusive procedure. Later.

Who can tell the difference between 5.9 and 6.2?

I'm never is such a hurry that 7.0 would bother me much.

JCtx

I don't care, so even if it was 7sec, I'd have bought it anyway, but guy wants 5 sec, remember? And according to magazine guys, a 0.3 sec difference is 'substantial', whatever that means. But I agree with you; I couldn't tell either. Take care.

Yeah, Tim, and add to that 7.0 all the time you'd waste talking to the cop.

actually the sc430 stock is already a sub 6 car. on my gs400 i constantly got 5.8 or so (and that was stock on 19s already)

and yeah, without FI, i think low 5 is the limit of the car, and that's on a good day imho

totally agree, that's why we need the supra rear end with lsd. that helps to put power on the gnd better

you could get a test pipe also. And instead of the SRT intake / ECU go with another intake or keep the SRT intake and use a SAFC to tune the fuel more. Also I dont know if you consider these mods, but an easy thing to do would be lighten the car up. IE take some stuff out or get a carbon fiber hood ect...

also get some light rims and some 285 tires in the rear on a 10.5 or 11 inch rear wheel? I am sure the added traction would be of great help.

LSD 3.76 GROUP BUY!!!!!! Hint Hint

powmax

i got 1735 kg(1/4 tank) = 3825 lb without me on the road... do the 0-60(real) in around 5.6-8 sec. without power braking at the start...

does anyone else weighed his car?
