How fast with this combo?

[Z28Driver]

This is all the stuff that i have or will be on my car by the end of the summer and i'm trying to see what this set up will get me.

1. Adj wastegate
2. SMC kit running 90 octaine (could i get 21lb's boost out of it?)
3. Fuel pressure reg
4. Fuel injectors (36 or 42lb)
5. Walboro 340 hotwired
6. Some type of drag radial
7. Powerstroke intercooler
8. Cold air intake
9. Throttle body bypass mod
10. Shift kit
11. Tranny cooler
12. All kinds of gauges/scanmaster
13. Passenger side airbag

I live at 4200 feet elevation right now, and i'm aiming for a mid 11 at sea level so that would be like a low-mid 12 here?

With stock turbo, your'e probably looking at a mid to high 12. i ran a best of 12.72 with stock intercooler and turbo. I see your running a powerstroke intercooler which is good, however, without the ability to run more boost because o flimitation with the stock turbo, i dont see you going any faster than a mid-high 12. Now if you bolted on a TE44 or TA49 with that combo id say your probably good for a high 11-low 12. Also, you should run a powerplate, it will help with he knock a bit. Of course these are my opinions and are based on my experiences so i could be wrong, and hopefully with any luck youll prove me wrong!

I would guess 13.2XX with traction being a problem

3" downpipe...very very important in your combo, and it won't hurt either to get the exhaust job done also

I'd think probably high 12's. Biggest things you are missing are probably exhaust and downpipe (as mentioned above) along with some upgraded rear brakes/cylinders to hold boost.

Need a good launch with the stock turbo to get into low 12's and I'd go staright to street slicks like ET Streets or Hoosiers if you are serious about getting some low times. Drag radials are good for the street and decent for the track, but you'll do best with the slicks. Although some do get good 60ft times with drag radials, its easier and more consistent with slocks.

My T has run a best of 12.2 with stock turbo and intercooler with a dutt neck. The only major difference was a high stall convertor. Removing the front sway bar will also help at the track. If you can get to low 12's with a stock turbo, then you'll be mid 11's with an upgraded turbo at high boost (23+).

Ok, i'm going to order the 3inch downpipe and chip this week.

In your first post there is no mention of exhaust work,so:::

NO you can't run 21 PSI,
My prediction for that combo(at sea level) is 13.4--if you are lucky.Not trying to be mean--just telling you from experience.

Boost and air-in and air-out wakes these cars up!!! Let us know your results.

Along with the 3 inch downpipe i'm looking at getting some kind of cut-out to be placed where the cat used to be. How benefical is that?
