hey i was wondering, can my stock tranny hold around 550 hp?

That depends somewhat on which tranny you have. We need your model and trim level. (update your signature when you get a chance).

If you have one of the hd models, you might be close, but you're still gonna tear the hell out of it. I know Turtle is over 400, and he'* still ok for now. Complinitor is pumping some juice, too. Maybe those 2 guys can weigh in here. Neither has the HD trans, but may have beefed them up. I know Turtle has been in his recently. it will move your car, but not for long.

550hp seems a bit high dont you think will?

Turtle has redone his inside and out, as well as the engine. Not sure about Complinitor, but with a stock tranny and 550hp....well I doubt it would hold together that long.

Where you gonna get 550hp anyway? Share the wealth! :P

well see i'm starting to race so i've got friends working on it but i'm going to port and polish the charger, new tb,cold air in,1 1/2" lower,lowprofile tires, new rims,big shot nitrous,performance cam, lifter/rockerarms,new valve springs, new pistons,ase chip,shift kit, looking at water/alc. injsection, also considering ram air
to begin with

A stock trans will not handle that hp but, a modified trans from Domestic Performance WILL! Talk to Ty!

I dont see how you are going to get 550 hp out of this combination. ZZPerformance using the Eaton M90 blower ported to the max with intercooler make 400HP at the crank and run a 12.0 1/4 mile. I dont see how you are going to get your car 1 1/2" lower... Even with all those modifications depending if you are Series I or Series II engine probably get 300-350HP (crank). Why put ram air on a */C car? Doesn't matter, still going to be heated up by the supercharger, a intercooler n with[/quote]

And doing those mods and have the ASE chips might not be the best idea, just letting you know, I live 1 hour from them. Their chips are more meant for stock cars, not ones that have been modified for more power.

As for you quesiton of hte tranny, not it really wont take too much more abuse. If you do not have a shift kit, it will be fine for a while but won't last forever. If you gave a better description of your modificatiowould be better. And an intercooler would be better than water/alc injection.

If you gave a better description of your modifications more, we can better guess how much power you are going to make then see if the rest will survive with the engine.

ok I love the sybol hector very zen.
I can tell ya yes your transaxle weather it is a 4t60-e or a 4t65-e can be setup to handle 500+ hp. Actually the 4t60-e can take on 400hp with only a few mods. My 4t60-e can take serious power but I charge an extra 500 ish for the limited slip. Basically it’* a blueprinted transaxle built to your needs. Remember any shop can blueprint your transaxle but there are certain parts we replace so you are even further ahead. Also the transaxle can be rewired for a grand am or many other applications where they stopped using the 4t60-e and replaced it with the anemic 4t45 or 4t40-e. The kit also comes with custom shift points and a custom torque converter. You name it and I can get it for ya. If the price tag is scary then take a caddy 4t60-e HD and with a few adjustments with a custom torque converter and a limited slip you can ride with 400hp. BUT once you have eaten two or three you can call on me and ill fix you up with the Best. We also do not charge a core charge.

P.*. we are supplying a few track car builders and they are our testing ground. I know form experience what the 4t60-e will take. 400 in a grand am with a few mods is ok but in a Bonneville you will blow it to bits more often than not.
