Can you verify intercooler water moving in the reservoir?

 

I’ll verify that today

 

How much boost? Tuned for 93? Factory hex cooler should be sufficient I'm still running the stuff that came stock with mine, I doubt that's your problem. Probally has to do with the fact your running a stock exhaust, blowers need to breath...

 

.mph?

 

I based my guess on my time when I had a boosted, IC'ed, 6.0. It ran 13.2@102 and 5500 lbs. I reduced the time because of my horrible 60' time, and you are AWD And I reduced the mph because I figured that you weigh more.

I have always had stock exhaust, that's not your problem.

I suspect it is a compilation of things. Lean, I don't how much can a BAP compensate for too small of a fuel pump. Tune, is the torque limited somehow or maybe burst knock? Your 60' times indicate torque reduction or knock or false knock. I never had luck with 7 heat range plugs, they only gave it crappy idle. I think I ran 6 heat range, good idle and no signs of being too hot (according to the NGK plug reading chart).

Yes you need to datalog while you're running just to see what it’s doing.

 

I went and check on my intercooler pump. I really don’t like where I placed it. At the angle it’s at, being a pusher style pump, it’s fighting an uphill battle to get the coolant through the heat exchanger. Plus the flow inside the reservoir is lack luster at best when the pump is running. I never asked my tuner any specifics while he was tuning it. He had to road tune it because he didn’t have an awd dyno. I had to drive 3 hours to him, on my only day off, so I basically told him to tune around whatever pitfalls the truck had because I wanted a one and done and didn’t want to have to keep driving back and forth. I have an efilive autocal v3 handheld that has datalogging capabilities but if anyone knows of a better datalog device let me know

 

So exhaust is pointless? You made me lol...

 

The V3 will be plenty if you have it setup right. Id like to see a datalog of just cruising around and a WOT pull.

 

I ran stock exhaust on my first turbo truck.. It worked but just changing the muffler helped a ton! So yea i can see a pretty good gain with a simple exhaust.

 

On my LQ4 with cam and worked 243 heads I get about 8lbs of boost with a 3.5" pulley on the 2.3L whipple. With the 3" pulley, you are probably pushing 10-12#s of boost. I am still on stock exhaust manifolds but run 3" duals xpiped all the way after. Best I could do with my old setup in my 4wd 2 door tahoe, with a race wieght of 5400lbs, was 13.9 seconds with my stock L31 5.7L intercooled 1.6L whipple at 10 psi of boost running 100% meth. It feels faster with this new setup especially on the top end but I haven't launched it in 4wd because I dont want to break anything and I am still tuning it.
