We had it at 13.96..Back to a minimum now. 5 tenths under. 15.10

The Ecotec engine has a lot of potential and will make great power when tweaked. In the shop I used to managed, we built them for off road racing. The engines built for the off road sealed engine class made easily over 215 HP on the dyno with the stock components and stock cam.

As an example , the Monte went 85 mph with 200k on the clock, 2.93 gears , pure stock. We figured that was enough to run the index at the time, so we went ahead with it.
It ran 1.05 under @ 94 on the first pass.
80 is probably enough potential to get you under the index. Biggest problem will be getting enough torque out of it, with not enough gear.
Might want to check if you can get 13" or even14" wheels on it.

These are round track racing wheels but they are available in the right bolt circle pattern (4 x 100) and are approximately 12 - 14 lbs.

Any advice on back spacing?

Having a harder time finding skinny front runners in that bolt pattern. Can anyone point me in that direction?

How did you go about tuning the computer Mark?

[Mark Yacavone]

We had Ed Wright remove all the limiters and the electronic transmission junk, and give it some more timing and fuel. Only tuning we can do is raise the fuel pressure, using an LT1 adjustable regulator. We use a mild street and strip style cam so that the vacuum signal is not outside of the parameters of what the computer can handle.
Stock ECM and coil pak.

Are the fwd's allowed to use a K&N style cold air intake?

Don't see why not, as long as you don't cut any new openings.
It might go faster with nothing on it.
In the dime rocket tradition, we just gutted the stock air box of all the baffles and anti- noise devices, and opened up the front of it some more. Ours holds the computer in the lower part, so some of it had to stay anyway.

Mike, are you referring the 2.4 Ecotec 4 cylinder engine?
I believe Mark runs the 3.1 V-6.


If you plan to run the 4 cylinder Ecotec, there are lots of different ECU platforms including standalone ECU's.
