Want more Torque

Although the request is for more torque, I’d say this guy (sscamaro387)is looking for more drivability and power down low, without having to string the engine out to 3,000+ rpm on the street in order to feel what he has paid for. Otherwise he wouldn’t be chasing a figure that realistically is a ridiculous way of finding more torque. Torque with his set-up goes hand in hand with horsepower and obviously RPM with this selection.
Realistically, when ever anyone has a complaint with torque regarding this style of set-up, you need to look towards the camshaft. On this engine (I’m sorry to say) it’s all wrong! The unfortunate part is, if the intake ports are opened up to buggery, you’ll be chasing your tail even further!
116lsa looks more like a choice made by someone who can’t tune.
Sorry for the simple reality check and I’m also sorry for the bloke who now has to battle with the problem of making it work for the customer. Dyno and strip? Yep it will go! Drivability…. No way! Hence the torque queries!

Hence the torque queries! His last motor with his cam and long tubes had a 10PSI setup, he made 10PSI all day, we built a forged motor and with the same long tubes, and a different cam and heads, the new combo was so much more efficient that he only saw 5PSI now with way more power.
If the case is a bit more TQ down low, then either a shoot, or a simple cam change can fix that. But as someone already said, the power goes hand in hand, you make more of one than the other.

My torque is only 10 foot pounds behind my HP. Gotta love those stroker. Once I put more than 9psi of boost into the car, More then 14 degrees of timing, rev it past 5500rpm's and run some meth, I should have another 60rwtq. That will also be with a SAE correction of course, not uncorrected =)

Correstion: I just looked out the Dyno sheet and it is 17 foot pounds

Yeah, thats what you get on a stroker due to the fact that it moves the TQ sooner in the RPM band. But longevity wise and price wise, for what the setup is, it makes awsome power while passing smog.

I agree the price is nothing to laugh over. But if you are going to do it you mine as well go all the way. The bad thing is, when you look at your Credit card statement at the end of the month.

Hey heath,
Yeah it sure has been a while. The new setup is working out well. Still have A LOT more tunning to do but the car is putting out 705rwhp@5500rpm's with only 9psi(SAE Corrected.) We hope to get it over 800rwhp with 13-14psi, meth, 6500rpm's, and more timing (only running 14degrees.) This is all on 91octane.
I see you have changed your setup. How are you liking it so far? When I get back into the Bay area (I have been living in San Diego for a year) we should get together. I would like to check your STS kit out.

sounds good.
don't go crazy with timing.
your probably where you should be now timing wise once you crank up the boost.
I highly recommend getting a progressive alky kit like the alky control one.
A lot easier to tune with.
STS kit should be rolling soon. Car has been sitting for months while I remodel my house.
