STS question

msdnga said:
With that 750 tune, full weight and 30" tall slicks I posted 11.3 at 126, why do I have to spin my combo to 6000rpm?

If I can run those times and keep the shift point below 5500, then I have zero oiling issues to concern myself with. You build for torque and the hp will fall right into place.

Not going to detail you on the twin till I run it at Speedworld. If you must have 5000-6000, you need to run a larger y-pipe before the T-76 to keep the backpressure lower.

I am sure with only 900 rear wheel, I will run 10.9o's all safe on the STS system. Sit back and simply watch....:rock:

You got Balls.....I like it. I wish you success my man :rock:

Mr Got rid of your Hemi---stop taking it personally, you did not design the Paxton setup. Forge your engine, install a SCT with a 2bar MAP and the correct injectors, then you will have a chance of outrunning a STS turbo that makes full boost at 3000 rpm, unlike a Paxton that makes it 3000rpm later.

If youd like to follow up on that challenge Im in Chicago, Majority of the time I put my money on a turbo, but I know for a fact that this truck ran a 11.20 at the track on the street tires. So if youd like to bring that sts up here Im willing to meet ya and see how good that system is. Heck well play on the street too. I bet even if you win, I wont be far behind. I didnt take it personal till now either with that chance statement, never say never. Im normally a nice guy but when you lay out a challenge be prepaired to step up. Additionally, you should know me, remember your the one who sold me a paxton that was used and missing parts, i asked you to get all the parts for me and you did not, you sent it like a pos to me not including it was satin but completely scratched up and covered in gas from the fuel pump, which might I add you threw in the box too, and when i say threw, i mean all parts in which is how I recieved it all including my intercooler hanging out of the other box! I had to sell it due to the mess it was in. :mad:

Well, lots of responses thats good. This site is really helping me plan my build. Still don't know the type of boost I'll be going with, but at least the motor will be forged. However, I most likely will stay with a stock compression ratio, but wonder if lower compression would be a smart move.

Lower compression will allow you to run more boost.
The down side, I think is a little loss in off boost power and mileage.

 
Im sorry to the other members here, normally im not one to air any dirty laundry but I took offense at the my dk is bigger than your statement from mr sts, due to what happened to me personally in dealing with him. I just blew a gasket a little bit, and couldnt stop typing. Im no longer viewing this thread and am done.

The only reason I worry about lower compression is, let's say I get the paxton system. With lower compression I worry I may lose some power on the bottom end of the rpm's. Everything I read says the paxton starts pullin around 3500 to 4000. How much would I have to turn up the boost to make up for the lower compression, and would it be harder to tune at higher boost. I know the real awnser to my questions is how much do I want out of this truck. Well, I would think 800hp would be awsome, and would probably be cool with that for quite soom time. At what hp do you need to start thinkin about lower compression? There is alot to think about, each system (paxton,roe,sts and soo on) can deliver the power different. I would love to have this truck pullin hard from a dead stop and just not stop pullin till you let of the gas!!!! If, I have to choose when the power hits the hardest, well, not sure yet.

With the centifugals the faster you drive it the earlier the power kicks in.
On my town car I started with 8psi, then 12psi, then 15psi at which time I was totally happy with the performance but it wasted the diff, then broke an axel, and now I'm on about the 5th trans rebuild.

If you go much beyond 150-200hp over stock you are probably going to end up having to upgrade other components.

If you don't You will be sorry ;) :D
 
Ya see, thats just nasty power!:burnout: I'll figure it out. Worst case I only make 800 hp, not to bad.

Yea that's what I get for being cheap instead of going first class to start with.:damnmate:

I probably have as much $ in labor as parts now.:mad:

Not worried, allready got the tranny done and will do the ultimate 60. Just want to make the right piston comp ratio choice. However, I do only have the centerforce clutch and don't think it will do well past 850.:D

If you got the cash to Mod....You better have the cash for a extra motor is all I will say...To correct an earlier poster on this thread...The STS system has not been the cause of the most engine failures on the site....Simple fact is more NA motors have been lost then all Modified motors combined. Do a search and educate yourself before posted blind ;)

The fact more NA motors have been lost is directly attributable to stupid drivers...Pushing the limits and using no common sense. You can fix a motor...It's the stupid part that has no cure :D
 
Marty do you just lower the shift points? What causes the power to drop off like it does? I understand why you are doing it, just trying to understand how you are doing it.
 
I change the springs on the intake, and modify the y-pipe on turbo builds over 650 rear wheel.

I wonder why 1bad4dr has not posted on this thread :dontknow: Now that I have pieced together who Marty is :mad: :mad:
