You're right, spelling is the key to all automotive knowledge. I better part my car out before I hurt myself.

I really don't want to get dragged into a rear mounted vs front mounted turbo setup discussion (especially since I'm in the process of building one for myself). However, if you're going to drop 3000+ on a FI 'kit' ... you should really consider other options including DIY your own rear mounted setup (that is intercooled) ... which is what I'm in the process of doing. Thats my only hangup on the whole deal I mean all things considered the PTK kits arent a "whole lot" more and you get some puuuuuurdy manifolds and a nice IC.

The two STS cars I've come in contact with had tuning issues for the most part. They were running pig rich. Also I just think most people if they spend some time could make a lot better looking setup *shrug*.

Otherwise they seemed fine, and on an automatic car like mine ... once its spooled it isnt going to spool back down. Boost is boost, and I agree the length of the piping isnt a huge issue... especially on a V8.

 

I agree, the PTK kits are awesome. No denying that.

I think once these STS kits are picked up by F-body owners, over time they'll "iron out" some minor issues, and get their tuning dialed in. Once these guys starting turning out some good track times, people will be a little more open to them.

 

No way was his IATs 100deg at 7psi. Maybe while driving NOT under boost but not under full boost that's for sure.

My truck saw 120deg IATs just driving around town and up to 150deg at full throttle at 6psi. At 10psi we were at 190deg and at 13posi it shot up to 230deg.

Hense the intercooler or methanol suggestions

 

The part about 120ft of pipe was just a bit of sarcasm. Just saying, I rode in the car, and honestly wasnt too impressed. From what the owner told me, the kit equipped that way would be about 4600 dollars or so.

 

come out my way and I will give you a ride, also for what its worth I made peak tq at 4500(615tq-10 psi) while a moderators car on ls1 tech with a fully built setup like mine peaked a 5000(540 tq-10 psi) and hes a t76 front mount. Posted his graph as well. There goes the old slow spool theory eh? Also he went 11.82, front mounts must suck cause his times sure do.I can beat that with 420 rwhp.(saracasm)

 

You keep talking about PEAK numbers here. What the dyno graph is doing before and after it peaks at those numbers is what's important. My TQ peak is at 4500rpm, but my torque curve is nearly completely flat from 3600rpm to that point. On the computer screen, my TQ peak is expressed as 2 pixels that are raised above the otherwise flat and straight line. Looking at where my PEAK is, someone could easily say my turbo has a slow spool time, but looking at the graph, it's easy to tell otherwise. Same thing applies to the system you mentioned... i'd like to see his dyno graph. Just guessing, i'd say it looks much nicer than the standard STS graph.

Another example would be Mightymouse's car. Looking at his graph, his TQ peak is somewhere near 4500rpm, but at equal power levels, his car would blow the doors off of any STS car, i'd guarantee that. Why? Because his graphs are very impressive.... not just his PEAK numbers.

 

come on ladies... power is power, yea one may be faster than other, but if everyone had the same thing... it would be boring....

See my graphs, my car peaks and holds to the rev limiter 6500, the t76 graph I have have drops after his peek. Mine does not. And for your info mightys car on pump gas and 14psi is under my power. Look for yourself. Btw your numbers are really low? Are you a 6 cyclinder? If so then disregard that. I like that, nobody goes that route with the v6, anymore info on your car?

 

if you look at there other posts 5.0 and him are friends, they religously bash sts kits when one doesnt even own any kind of turbo car and the other qoutes other peoples achievments. No biggie though, it makes them feel better.

 

So the basic jist of all this is....STS kits can make good power. Also, there are people who like them a lot, and there are people that do not like them much at all.

I agree, flat #s look better

GT35, no IC, meth injection on a 5.3L with 226 cam.

 

the scale is helping you out a bit nonetheless nice curves. Not surprising since the kit was made for trucks and seems to work better on them IMO.

 

True. Wish we would have started the run earlier though. That way the spool up time would have been more evident. That GT35 spooled decently fast. The GT67.... well is spool time on the 5.3L is

 

Why is it you think they work better on trucks. I never understood your thinking when you always seem to mention that? Trucks have longer piping and larger exhaust pipes then the fbodies, so how is that gonna help them perform better? You say that is the down fall of the fbody system (rear mount, too much piping)?

 

Doesn't the PTK kit start about $1200 more? Plus, that starting point DOESN'T even include the turbo.

Are my figures accurate?
