FPV GTHO

170-180rwkw would be my guess.

I gained a tenth on the quarter mile with my underdrive

The figures seem ok. My car had a 2x2.25 exhaust, growler, under drives and manifold spacers and it ran 160.8rwkw. That was a BF and I was hoping for more. It later ran 175.9rwkw with different extractors and a ported intake manifold.

Stock turbo exhausts on NA's are fairly proven. Keeping the stock manifold should mean theres no power or torque loss anywhere. Theyre supposed to be quiet at idle and loud at WOT but ive never liked my B series one particularly, and I'm looking to stick on a Di Fillipo 3 inch single at some point in the future.

You can usually get at least 30rwkw from tune I take and exhaust.

Those figures look like they're from a 4 speed. ZF NA's can do 400m in 14.5s

A genuine 200rwkw 5-6 speed auto will go alot better than mid 14's. My 175rwkw 4 speed can do 14.5 in street trim.

Don't waste your time with the 4500's. they're designed to fit with the cat in the stock location hence the weird design. Just go 4490's for a cruiser or 4495's for some fun.

Haven't posted on here in years. In that time I've picked up a 2007 XT 4spd and its sitting at 175rwkw untuned and 14.2 qtr mile.

It could be the case, the fault seemed to be in the carbon fibre carcass (the reason why Bridgestone didnt have issues) so I guess they were hoping the harder Barcelona compound would prevent problems

They were different tyres actually, Michelin brought over another batch of "Barcelona" spec tyres from Rnd5 which wouldve been a completely different compound and construction. The FIA said it would be a breach of rules to allow the new tyres as they werent presented to scrutineering earlier in the week, but ultimately the decision was up to the race stewards. Considering the FIA felt the punishment wouldnt be exclusion, it adds some more blame on the teams.

I always thought top fuel run direct drive, as they cant affordably make multi speed transmissions that are both strong, smooth and fast enough to get a car down the quarter. In any case, they usually run half the strip still on clutch slip anyway, and are literally hitting max revs right off the start line.

20,000 should be no problem for a manufacturer such as ZF. If they cant supply that many more, they shouldnt be in the business. I think the Territory Ghia will even get the 6 speed at the end of the year.

It'll be on more than just the FPV's, the XR6T, XR8, Fairmont, Fairmont Ghia, Fairlane Ghia, G220 and LTD should all get it as well.
