    Fuel pump upgrade

    Danny, according to all formulas I know is it enough for 800-900hp. The psi does not have much to do with needed flow. This is an interesting article on the subject. http://www.kennebell.net/media/articles/FUELPUMP.pdf I do use a Boost-A-Pump and a 255 l/h pump. /JP

    Porting and polished heads

    Porting (no polishing) + 2.00/1.6 valves, Bronse guides, springs, Crome Moly Retainers, Chims, Roll lifters, Arrow 1:7 Rockers, Crome Moly Push Rods, Billet Camshaft 110-114 lobe, 220/220? duration, 0.550 lift. Is what I would do. Would never take the cost of lifting the heads without the mods...

    Fuel pump upgrade

    A Walbro 340 (255l/h)is used by most turners. $110-140. Or just install a Kenne Bell "Bost-A-Pump"...or both :-) I would plump the intake and build a return line with a pressure regulator aswell.

    How Many Gen-1 Original Head Gaskets??

    It takes about 1 day to do it. Gaskets. Oil + filter. Coolant. That's all. I would say $1500 is a decent prize. /JP

    GTS-R V10 to V8 change

    Half of our team is racing the FIA GT series with a GTS/R Viper. According to them is the plan to use the Mercedes Benz V8 in the Vipers for next season. Mercedes and Chrysler is the same family now, so it is ok to change engines (Family business) according to the FIA rules. /JP

    To loud, which muffler should I install?

    It is with Belangers, no cats, 3" pipes and Race Bullet mufflers. Had this set-up last year with stock engine...sounded tame, but now with the new engine it's way to loud to be driven on the street. The engine is built for nitrous abuse.

    11.18 @ 125...Ported Heads, Stock Cam, Drag Radials...how's it compare?

    Re: 11.18 @ 125...Ported Heads, Stock Cam, Drag Radials...how\'s it compare? I would ad a set of Belangers and a 3" pipes, the should the 10.9 be safe. I'm running 10.7s with a similar combination in my Gen1 (+ camshaft)

    How Many Gen-1 Original Head Gaskets??

    When my gasket (one side) started to leak, did I just retorqued it, worked fine for me. You don't need to remove the rockers. I changed my head gaskets this season, but that was because of other reasons.

    To loud, which muffler should I install?

    I'm rebuilding my exhaust system and need input on a muffler that really work well in the limited spaced side sills. My Viper is far to loud as it is now. I want a straight through design that don't rob any power. Sound file www.venomousracing.com/upload/Sound_large.wmv Thanxs /JP

    Halfshaft replacement time.. any input?

    Just unbolt it on both ends, remove it, use new straps and bolts for the new half shaft. Don't over tighten. Use a 8mm wrench. Check so that the CV joints moves smootly, if not relplace them.
