    Stroked vs Bored

    Just look at a block. You can bore it out 0.100" but you'll have smoke coming out your exhaust pipes in no time. You need a certain amount of metal between bores to not only stop cracking, but also to keep the bores straight and round. If you go too thin you can't have straight/round bores...

    Stroked vs Bored

    you can bore - but .030" is the max, and that is your last size without having to resleeve the block and start again - not a job for any but the best machine shops. The point is this - 0.020" over-bore makes sense - it allows you to blueprint the bores on a used engine, yet leave one more...

    Who has the most powerful srt here???? post dyno sheets please

    There's a small handful of twin turbo SRT10's floating around that make 4 digit power at the crank - and that have a pretty low profile right now.

    Stroked vs Bored

    If a certain capacity is desired - a big bore is the best way to get it if you want an engine you can lean on hard all day. Despite all the theories out there, reality is the big bore engine will make more power than the long stroke engine of the same size and have increased rpm capability...

    TT Turbo Questions

    :D you don't need to worry about no Busa Chad! You've got those things covered with two parallel turbos :2tu: I don't think you'll run out of boost on that setup anytime soon :D

    TT Turbo Questions

    and to answer another question - all current TT Vipers I know of use one each bank - same size each side. Nobody has done a twin in series yet - but that is just a bad idea on a 500 cube engine anyway unless it is for all out racing and you are using one to preboost the other. For street it...

    six second quarter mile...

    That was epic. That is the quickest 6 cylinder I've ever seen - very cool, and I think that would take out the quickest Skyline powered run. Both the Skyline 2.6 and the Toyota 3 litre engines are capable of about the same power - both very very good engine designs. I really look forward to...

    TT Turbo Questions

    You are correct. AEM allows you to do that. It also has traction control capability (which has not been used yet on a TT to my knowledge). Most tuners keep their turbo sizing to themselves - but they tend to be similar to each other as the space is tight where they are most commonly mounted.

    Has Anyone Used Heat Wrap Around Their Ehhaust (Inside Rocker Panels)?

    Be careful, you may need high flow cats to handle the heat, and insulate anything unwrapped that touches the metal. I've wrapped other vehicles with success from front to back - both reducing drone and keeping the heat within the exhaust which reduced heat soak into the car/engine bay. Pipe...

    Greg Good gives good heads! -- pics inside!

    Nice heads! I agree with what Greg and George have said. A 5 or 6 axis CNC machine can clone a fantastic port by digitizing it and get very close, but a great porter will always be able to make some improvements by hand on individual heads because it is an art rather than a science. Maybe one...

    2005 SRT-10 Baseline Dyno Results (pic)

    Best way to break em in is to not chug em at high load - but let them rpm through the gears - first at partial throttle and let the rpms build, then steadily feed in more throttle, until after a few runs you are pulling WOT thru the gears - yes to the redline! :headbang: By 20 miles the...

    Changing Wheel Offsets

    Ignoring for a moment the obvious re-engineering issues - say we could change the wheel offsets in the Viper from almost flush mounted to deep dish wheels and everything in between - while keeping the same contact patch and same track width. Questions: 1 - What changes would occur to the...

    TNT rear mount turbo

    that would be wrong you tend to get what you pay for... if you disagree - a 12 second Camaro is always gonna be a better deal than a 12 sec Ferrari! Many would agree I don't.

    Question on coolant flush

    Just before I left Neew Zealand to come here I met an inventor who had solved a problem that has largely gone unrecognized with water cooled engines. He brought his invention over to my place and he demonstrated it for me. I think there is a huge potential for it here and around the world -...

    ME Four-Twelve based Viper Coupe Concept

    meanwhile - back to the real ME-4/12 :D several jurno's have now test driven the protoype and come away very impressed considering it was detuned for them and has more weight to come off yet... The car has achieved sub 3 seconds 0-60mph by DC, and has braked at 2g and cornered at 1.5g -...

    Vacuum pump tech; free up that hidden horsepower

    Re: Vacuum pump tech; free up that hidden horsepower I don't know Joe - I accepted the usual answers about reducing ring blow by... your questions are good but I don't have the answers. It's like we used to pick up 6% at the wheels on muscle cars and hi perf carby engines by fitting large...

    Vacuum pump tech; free up that hidden horsepower

    Re: Vacuum pump tech; free up that hidden horsepower Joe - racers do not typically bother themselves with the science behind why some things work. After satisfying themselves there is some logic to why they should try it - the only 2 things that interest them are: 1 - will it hurt anything...

    Viper SRT-Coupe Production Changes

    Great work - and I agree. The CC coupe is a far cry ahead of the concept coupe in looks. By adding more curve like the Gen 2 GTS in the side and rear vents it'd be awesome. The only part I never liked about the Gen 3 is the ridge along the top and especially as it passes the rear roof...
