It's looking like 8000 she won't be too down on power so maybe around there. That should keep me in the meat of it.

Just waiting for the new 4 lane, all concrete Concord (Zmax) drag strip 10 minutes from my house and 3SX to be completed in September. Then I will see what she's got.

You would be suprised Trevor, the street car's race weight is in the area of 3350 ish at race weight and put down 540 AWHP and has run a best of 9.9@137.7. It just uses the avaiable power well.

FYI: My estimated Octane with the Race/93 pump mix was 102-103 Octane.
I think just straight 110 may yield even better results.

So when you bumped the cam gears did you re set the timing with a timing light? If not you added timing as well.

Copied from my E85 thread.
707AWHP 620AWTQ Stock Heads Stock Cams Pump gas

I think this pushes the 2 bolt pretty hard and pushes the stock heads and cams past 700AWHP.

Ok, most would not call E85 "pump gas". While is is available at many gas stations at the pump and normal cars (flex fuel) use it it's really not "pump gas".
But makes for a funny thread title.

It was finally time for me to test out E85. Been wanting to for a long time, before I started building my DD. For those unfamiliar with it, it's about 105 octane but acts better than C16. It's burn characteristics are great and it cools the charge. Makes more power than race gas all for cheaper than 93 octane. Well, you do run about 30% more E85 then Gas, but when compared to race gas it's the hands down winner both in performance and cost.

I installed a dual pump dual feed system a few weeks ago. And today...I found it it does even more than expected.

I did base runs on the tune it was siting at at wastegate pressure/boost controller off, 14psi.

Then dumped the VP110 and put in the E85. NO timing changes were made at this point, All that was done was retuning the fuel map to hit the same AFR. You will see the AFR on the VP110 run matches the E85 run. The increae floored me.

Then I slowly turned up the boost until I hit the 24psi/625AWHP area that I hit a wall with on the VP110. Again TQ and HP were up. But funny thing, the HP wall disappeared. I kept upping the boost and unlike the VP110 that stopped at 625, It just kept going. 644AWHP, 660AWHP, 676AWHP.

Then I set it to 30psi. Held on. And Went.

707AWHP 620AWTQ. Out of Stock Heads and Cams.
the run was quiet but we are getting to that 30psi high HP area where heads start to lift so I ended he session there. I am happy with 707AWHP.

As known, E85 cools very well. With VP110 the coolant was getting to 207F at the end of 14psi runs. With E85 I could run 600+AWHP runs back to back and she never broke 193F, and next run would dip right back to 180F without a long cool down.

Car showed the extra power peak and the Gobs of extra power under the curve on the street. As many have mention in many articles, it seems to run smoother. The Pull under power is smoother. And it smells sweet while running.

Corn Kicks Ass.

Good job i bet she flys

I'd be more worried about my crank...

Great numbers again Chris, did you post pics of the car completed yet?
