After a year I got the car to the track.

60’---1.848
330---5.02
1/8---7.731
Mph---90.69
1000---10.0625
1/4---12.022
Mph---115.35



60’---1.848
330---4.982
1/8---7.596
Mph---93.56
1000---10.131
1/4---12.651
Mph---87.43 (miss shift)

I love it 115.35 mph...small turbo and all runs 19# of boost with 24/22 timing and no tuning. A lot left in it!

Thank you Jack!!!!!!! I could not be happier.

Your welcome Walter, great to see you do well. RPE builds an awsome motor. He deserves the credit, his motors are nothing short of fantastic!!

Jack,

Took the car back to the track and changed the plugs to 104 and it picked up 4.61 MPH!

60'----1.675
330---4.730
1/8---7.340
MPH--94.46
1000--9.583
1/4---11.470
MPH---119.96

This was done @ 18 psi!

Thanks,
Walter

I changed the plugs to 104 because they looked like they were not getting hot enough IMO. I'm only running 17-19 psi.

Way to go Walter, good to see the improvements. I doubt it's the plugs though, nothing wrong with the 104's, they just fit your tune up. I would be more inclined to say atmospheric conditions and possibly different tune had more to do with it.. keep up the good work, slow and steady usually wins the race.. :smile: and saves on the pocket book in the long run..

I dont really think this tune was different than the 1st time out but I'll take it. First run of the day and it turns an 11.47...I cant believe I did not get kicked out, no cage. Thanks Jack I'm happy!
