Best Turbo Setup

[HellBringer]

AWD traction issues at 500WHP...!? You must either have comically shitty, undersized tires, or a serious alignment issue or some combination thereof.. Seriously.. I can hook mid 600WHP on a RWD car on 19" street tires. There is absolutely NO excuse for 'traction problems' on an AWD car unless you're making serious horsepower.

Todds DR750 car would literally smoke all 4 tires through first gear(could actually see the smoke from in the car..lol) and end up in the other lane if you werent careful. Yeah not the best tires...lol And if you spun through 1st it would keep em spinning through some of 2nd gear.

If you just rolled into it and floored it in 1st into 2nd it would hook w/o drama, but launching it was very delicate.

The coefficient of kinetic friction is less than the coefficient of static friction.

Translation, you need better rubber.

The rears are on the left. They were essentially brand new, that was done in 2 nights over one weekend car show. 25-26psi on the 750's stock longblock.

That, and - once spinning you will continue to spin!

That's just the car hinting that it wants slicks....

There's an easy solution to that problem. Stiffer rear suspension and less camber in the rear would've mitigated a lot of that wear, and increased traction. You need to eliminate the squat and resultant severe negative camber, and it will stick a lot better. Just because you have AWD doesn't mean you can ignore the basic fundamentals of suspension and alignment setup for traction. You can get away with that at the power level 98% of the cars have made since the beginning of time, but once you step into big boy power (550-600WHP+) then it can no longer be ignored. AWD without traction is not fun, and not safe; at least without the a significant rear bias, which these cars don't have.

Good observation.

Alignment and suspension work would really help. Adding to that, more than anything there appears to be a big gap in tire compliance. From a glance the tire appears to be 9" wide. The tread gap in the radial design water channels appears to add up to about 1". The inside shouldering is stealing about 1.25" of outside field tread in camber transition. I'm guessing the effective grip footprint of the tire is only around 6.75". No surprise at all doing burnouts with 7" of tire contact tires and 500hp. Todd is only using 75% of the tires potential footprint.

The car now has Megan coil overs on it. Rides like shit now compared to stock struts and Tein springs. But we still havnt gotten this POS working right despite putting every single correct part on the car, so no real results yet with the new suspension as far as hooking up. Also running much better tires now and wider section width.

Just an observation with normal tires and 500+whp...spin fest, was a lot of fun though..lol On the streets even considerably faster rwd cars were still easy pickins.
