Inliners International Forums General Discussion Blown and Injected turbo 292 write up

You are a quick reader!

I have the cams instock.

The factory GM computers would not allow you to really tune the engine. The Holley one I use allows plenty of tuning capabilities. And it is easy to do.

I use a inline fuel pump for my application, it will supply all the fuel ever needed. You will most probably need add a sump to the tank to get rid of fuel slosh. Use the old fuel line for the return.

Here is a update for everyone else.
After dynoing the 292 and the 250, I have finally got some time to work on the ELCO.

A reminder, My engine is multi port fuel injected and I found that it ran better with divider plates added to the intake ports. This inturn made the intake port window too small, yet the car responded well and recorded a time of 13.8 in the 1/4 mile. This is a street car, just weighed this week @ 3700 with me in it. It is ran down the track in drive and shifts at 4800 RPM

Well now I have machined a head with a much larger intake port. It is taller and wider. A much better designed divider is installed and the engine was running fine before the convention but I was chicken to drive it 1100 miles each way going 75 mph not broken in or untested. Over the last 2 weeks, many miles have been put on it. The tune has been improved and let me tell you , the engine has changed! Used to run 11-12 PSI at full boost with old head, now it runs 7 PSI and has more power. Hope to take it to the track Fri night for test and tune runs. Will also see about getting that boost pumped back up. Tom
