worse gas mileage

Heat and your street low end tourqe will suffer. Dispite our popular vendors say, I would run a trans cooler.

 

[horist]

definetly run a trans cooler... I see no ill effects from bigger converters unless that grin I get every time I nail it is bad hehe

My problem is i can't stop... 3500 to 3600 to 4400 and now I wanna 5000 heh

 

[xttc2000]

its not going to help much IMO on a street driven FWD car.
how much trouble do you have hooking up right now?
itll be MUCH worse.
now on a tire thats another story.

 

[syP]

holy crap Mike... 5000??!@?@!?

Get a GT converter and be done. GTs have a bit higher stall than the stock GTP.

this is very bad advise!


ONLY drawback is heat.......run a tranny cooler, any size will do.

Low end torque doesNot suffer, power band changes

HTHs

Not all the Grand Prix vendors recommend against a cooler. We've been recommending them since day one. For a track car that's strictly 1/4 mile and is trailered to and from the track a cooler is useless but some of the vendors forget these cars are daily drivers.

GT TQ can not handle the power L67 produces, now if you get one with the same stall as GT you're good

 

[Fish]

Gotcha. I just said that cause I have read instances where a few people on clubgp just get junk yard GT trannys and throw their HD difs and dif covers on and bolt it to the engine.

 

[Kyle]

also heard of people using sunfire convertors, thats dumb if u ask me.

so what would be a good stall to go with then?

i drive the car daily, but dont rely on it to be a daily driver. I dont mind the gas mileage part really, i'm just looking for a nice gain.

what would be the downside of getting like 3800 compared to something smaller?

my intention is to run this year blown, but next year see what i can do with a turbo, so thats why i've been looking at such high stalls.

wont be in the market for something like this for a little while, i just wanna know what i'm doing when the time comes.

 

[CoolGTX]

the sunfire/gt torque convertors will Not work for Long in our applications! Either get one made, or get one from ZZP.

stall= higher RPMs it takes to move the car.

stock will move the car at say 1800 rpm, mine with the 300 stall, wont move till like 22-2500. Between the stall and the 3.29 gears replaceing the 2.93, my power band has risen. I also now stay in the powerband when the car shift gears, since it will stay at a higher RPM, after it shifts.

does that help?

edit....so, with all the constant higher rpms(= more heat), I DO recommend a small tranny cooler, for daily driven cars.

 

[Royalgtp]

I have a tranny cooler in mine as well........



Yes, my power band seems more "instant".......before when the car would shift it would feel soft for a second then get to the higher RPMs.......

The real advantage of an aftermarket convertor from ZZP or Intense is the fact they weight nearly 7lbs less than the stocker. This means less rotating mass and 7lbs @ 6krpm translates into alot less weight to have to move. This prolongs trans hardparts and frees up a few more ponies too

been looking at electric water pumps recently too.

whats everyones thought on that?

My only reserve about a new torque converter is the abuse that it will put on your tranny. With even a built tranny on this car that just adds to whatever it is that will end up destroying it. Especially with a turbo.


the nice thing about turbos and TC is that you can put load on the engine while staging, and build up boost before you leave the line. But that is just that much more power being shocked on an already "weak" tranny.
