does anyone make/modify a 5 or 6 spd automatic transmission to handle 1000 plus horsepower...they make the 4 spds...i have one.a modified 4l80e....looking for a 5 or 6 spd..

thanks

for this car www.forceperf.com 7.0 liter hemi with lot's of boost...

does anyone make/modify an a580 5 speed transmission to support 1200 h.p.?

good point, Indy Cylinder Heads is building the engine to handl e 1200 hp...

I have a 6.1 liter dodge hemi, i need to modify the intake manifold to accept a twin screw or roots blower. I want to keep the height above the hood as low as possible, so my question is, when cutting the manifold is there a minimum height it should be for performance, or does it not...

as i'm getting close to pulling the trigger on parts..i'm trying to figure out the smallest size blower i can use for the system...whipple makes a 5 liter...a bit smaller than the 6-71 in physical size as well.and has a rear air intake which is nice...any thoughts as to whether the whipple will...

that's a good thing i presume..:)

as a follow up...i'm assuming a twin screw supercharger would work the same as a roots in the twincharging set up..yes?

so you are saying that someone makes a blow off valve to regulate pressure for centrifugal superchargers?..do you know who?...it has a blow off valve now, but that is obviously for throttle off conditions...

assume i want 9psi boost..i have a centrifugal supercharger...it puts out 9psi but i want it at a lower rpm..so i put on a smaller pulley...does the job..however at the higher rpms it produces too much boost...is there a way to blow off the extra boost?...similarly to what a wastegate...

like i said this is fun, when you talk about positive scavenging and valve overlap, i presume you are referring to the exhaust stroke of the motor, where some of the intake is actually blown out the exhaust side, right?..i can see how that is affected by cam duration, but how is it affected by a...

thank you...looks like the 6-71 with gt45's...here's one for you...do you think i should inject above the roots at all for cooling and lubrication?...i could run 8 above and 8 below?..

so in our example if we have taken a theoretical shot at the roots..6-71...at about 1:1..i'm thinking gt42's..as a start...for the turbos...

patprimmer no apologies needed..i'm learning..i love this stuff..and i am very fortunate to have found some incredibly talented engineers on this forum....

i think i got it... 454 cid motor, 436 cid roots...at .74 crank produces about 6.2 psi, thus virtually creating a 653 cid motor..so i need two turbos whose combined boost gets to 10 psi(goal 20 psi overall). 6.2 s/c + 10 *1.4 turb = 20.4 total boost...in terms of sizing turbos...each of them...

Is 20 psi 20 psi?... Here’s my question...my goal is to move the torque curve left, up, and keep it flat as possible throughout the rpm range, and I’m looking to produce about 20psi..so.. With the twincharge set up, I can generate 20psi many ways..there are several permutations..the waste...

let me confirm this... so.. if i have a 454 cid motor..227 cid per rev..and i mount a 436 cid roots blower to it..that..i now have a 1.92 multiplier at 1 to 1. which means then i have a virtual 872 cid motor, 1.92*454..and at sea level ..on paper..i am producing approx. 14.7 * .92 or 13.5 psi.

ok..on a 454 cu. in. motor..if i run an 8-71(568 cu.in)..at 1 to 1...i get about 10 psi...that's about 1.67 - s/c to engine..568 into 227 .. so if i add 10psi of turbo boost to the intake of the s/c...then on paper i should get 10 * 1.67 = 16.7 + 10 or 26.7 psi of boost...right?....

ok, how about sizing for the twincharge or in my case tricharge, is there a methodology to do this..for example, 500 cu.in motor, 1400hp at flywheel desired...size of twin turbos...size of roots blower...i'm assuming we want to underdrive the roots... this is what i was thinking.. two g35's and...
