430hp 450lb tq hold on to your shorts

#2, The txchange kit sounds like valve bodies, etc, which will increase the longevity of your transmission, but won't really give the gears and clutches any additional ability to handle more power. By firming up the shifts, it will give you the most out of your existing transmission because it is reducing slip time.

I'm begining to think that there is no hope for the auto stick to go past the 280 ftlbs of torque barrier. However I'm also wondering if there is a way to get the horse pwr and cap the torque. For example. lets say I swap the turbo and get one that capable of producing 375 HP and 375 ftlbs of torque. Maybe it could be "tuned" to produce 325HP and 280 ftlbs of torque which would get me into the high 13's. What do you think?

Sounds good in theory, but in practice this would be pretty hard.Besides, without torque you have no HP, so how can you raise the HP without raising the TQ ? Even if you could do it, HP without matching TQ is just about good for nothing short of very looooong runs, and even then only on the top-end.

Do a search by using the word "torque" and at the same time enter "3BarBoost" under the search by member category. You'll come up with a number of topics where 3BarBoost discussed the torque capacities of both manual and auto trannies as well as clutch capacities.

Basicly 3BarBoost stated you could go about 20% over rated torque capacity and still have the trans live for 100,000 miles. The main problem with the auto trans is the multiplication effect of the torque converter where at launch the converter can more than double torque, his recomendation was to lower stall speed if your going to increase power above Stage 2 levels.

Do the search as I indicated above and you'll find it to be a very informative read.

I would like to raise the HP without exceeding the torque. There is a point at which we reach max torque. I would just like to have the max HP to go along with it. As for the HP without the matching torque, now you are getting it. I have enough HP and torque on the bottom end. I need HP on the top more than I need torque. I launch good, and get away quick, so I need more top end HP.

You can increase HP and move the torque higher in the RPM with a Biger turbo, It will create a big turbo lag. this will create the torque increase in the lower RPM range to be minimal but lots of HP in the high RPM range and increased MPH at the top end.

You can also use Honda Theories, they increase HP but have low torque numbers. They do this with lots of fuel in the low RPMs and leaning up in the High RPM with an A'PEXi S-AFC and a a V-AFC. they also do it with small bore, long strokes...

You may need to increase the RPM range so you can increse HP thru RPM...

It can be done but it will cost a lot in time, money and reliability.

Thanks Ian. As usual you make it easy to understand. So it looks like us auto stick folks that want a turbo upgrade had better start to beat the bushes to see what's out there.

Thanks macster.

I have seen this Toque/ HP issue first hand on the track.

I raced the other day with a Toyota Matrix (yes, a ricer)
I should have beaten it easely... I wasn't like that actually.
At the line, I launched ahead, I was winning untill the other driver hit fourth, No torque at that point, He jumped ahead and passed the ET lights at 98 MPH I did it at 91... Bad day for me.

I had biger displacement (2.4L) than the other car an a lot of toque (265)...
He had a lot of Top HP (230 WHP), six gears and low torque (170)... I got him at first but when his HP came online, it got me.

He was making 230 HP at the wheels, 170 LBs of torque. also he had a lighter car.

Also he was revving up to 7000!

Torque is half of it, If you already are spinning the tires but choking on the top end, what you want is HP not torque. The only way of doing this is moving around the numbers higher in the range.

Would this be something that could work for us

Give em a call/email. I've had nothing but bad luck. I don't want to jinx this.

Ian this is good stuff. But it looks like we are hijacking Tommy thread. I'll talk to you off line about this.
