If he is in colorado like i think he might be...The best track in the area (Bandimeer) is 6000 feet in altitude. Ive raced at the track before, and 6000 feet sucks ***!

 

The times in his sig "CORRECTED"...

 

Oh I neglected to see his dyno numbers. yea 115 trap seems off from being close to 500rwhp.

 

My best time in Colorado was 12.5 @ 108 this was at 6000 ft. The time in my sig is corrected. The dyno numbers are from a DynoJet dyno. The car will be setup the same way for the comparison. I'll keep you all up to date.

The reason I went with meth instead of a intercooler is money. A good air to water intercooler isn't cheap and I know of people having good luck with the meth injection so for now thats the way I'm going. I will most likely add a intercooler later on.

Jon, good info. This isnt a slam at you...I am just going to make a point below.

Littleredz, 5.othis and all the sts haters, I guess vortech's just dont work just like sts doesnt work...

Here is a 6 speed ls1 with 507rwhp trapping 123mph in hot Las Vegas with 0 boost at the launch. LittleredZ trapped 125mp with ~20rwhp less and he was probably had a better DA' then the sts guy. Worse case is they are similar in performance, but by no means does the sts kit not work at the track.

 

No actually i think vortechs are great i would love to have Ysi trim over a d1 anytime, but i got a good deal that couldnt pass on this kit.

My point being is yes my set up is a little more sirious then most of sts lt1/ls1 guys running at this moment but, as stated earlier when i was having issues with making boost and tunning, i only made 480 and traped 125 with stock suspensiong and rear with a 2.0 60ft i'm sure if i had a 12 bolt and set of QTPs like in my sig i had at the time, with a 1.5 or better 60ft i could of easily traped 127-128 range with 480rwhp.

 

I thought this was pretty clear...perhaps people dont realize what the full combos are, or perhaps somethning isnt right with the car. I have seen a ton of sts dyno graphs where the valvesprings were too weak and the car made peak power at 5000rpm and fell off dramatically. Well, if theses spool up to full boost by 3500rpm (with the smaller turbo) and die at 5000rpm, that goes to show why they dyno high, but not necessarily run great at the track. Powerband is too small. Once issues like this get fixed and you open the powerband up some the numbers will get better.

Point is everyone assumes it doesnt work. Of course it works, it makes the hp/tq. The key is setting the car up right based on how the sts likes to make power/tq.

 

Since were still comparing....

<-----Here is a 6 speed LT1 trapping 130mph in hot Florida with a small p600b Procharger.

 

BINGO!! If you see my dyno graph, you can see where the valves start to float. Right at 5100 rpm. I know this is going to be misconstrued as an excuse, but someone,comparing the 2 options here, may want to consider upgrading the valve springs at the same time as the install to avoid this problem. I am actually going to turn down the boost to 6 psi, and tune accordingly, to try and get more time in the powerband. At least until I have the money to get the valvetrain beefed up. As it goes with any FI car, the list continues to grow.

 

NIce! Info on the combo please...

 

Yep..and that car is a beast. I am very good friends with Jeremy. One hell'va guy and that's what my DIY turbo kit is being based off of. That's why I laugh at the STS haters on the board.

 

Interesting. I ran 7 and 8# of boost on my car with a P1SC and didn't have valve float. I'd be willing to bet one of the two are causing the problem...

1. restriction after the turbo hurting you after 5100rpms
2. plugs/wires/tune

99SS-T on LS1 tech had the same problem...swapped out for better plugs with the a .030-.035" gap and new plug wires and no more problem.

I know I saw another guy post, I think it was here, that he disconnected his muffler that was after the turbo and it solved his problem.

 

Turbooooooooooooooooooooooooooooooooo
