Only issue is a high idle, no vac leaks, appears throttle cable or throttle bodies are sticking alittle and not letting the blades close all the way. A small tap and it goes back down to 750rpm.

Pete,

Just plan on something much faster than your car, especialy since no one will be there to verify my speed. I will search the dumper for timeslip in the 10s.


Sorry you guys couldn't make it, but I guess they don't let you run if you're wearing a skirt.(when all else fails try provoking ).

Paybacks are a *itch, but car and driver ran like sh**. At first I could not get it to hook, as most could not today. My best 60ft 2.09, and my shifting sucked. Best overall run was a 12.87 @ 114.29.

One run was 13.01 @117.47.

HMMMMM......all that porting did not pay off too much.


Last year after I had everyhting sorted was running as fast as 12.54....with slowest times my last day at 12.8.

Back to the drawing board.

Lee,forget the ET is there a differance in MPH.
If you picked up about 2 MPH that's about 30hp.

I don't really like Byron there clocks are wacko,i guess i wouldn't expect any better from a weekend track.

Pete,

Right now both Lee and I have experienced similar results with Trap Speed being nearly the same as before the P&P. Unfortunately, neither of us benchmarked the hp on the motors before this winter although I doubt my motor was making 387rwhp before P&P. And the hp/tq curves definitely show a higher peaks for each of them. I think track conditions have a lot to do with these results so far. Both of us are running street tires and BG was not hooking. They sprayed the VHT once and that was it.

MPH were all over the place: 113.45, 111.34, 114.29, and 117.47.

Very inconsistent, need to get with Dominic to run a scan and see whats going on with the car.

Lee,what RPM are you shifting at?
At 380-390 rwhp you should run about 116-118
Did you run both lanes? either way,what is your 1/8 mph and 1/4 for each run.

The couple of times i raced at Byron one lane was wacko compared to the other.
I usually run very consistant withen tenths 2 times i ran at Byron the left lane i was running 94MPH 1/8 the other 97+.
The lane i ran 94 1/8 the 1/4 MPH was 124 the other lane i ran 98 1/8 the 1/4 was 121,same day.
The other 2 tracks i run,both have me at 97+/124+

Now i know my Z does not pick up 31mph on the last half and 23 is way too low.

60ft is ET nothing to do with MPH if you noticed some fast ZR-1's at BG were not getting the ET but the MPH was still there.

If you are looking to test your power Byron is not the track for it very inconsistent.
I have raced plenty to know that in my opinion Byron is just a fun track to hang and practice shifts not a test and tune track,unless you wanna go bald pulling your hair.

My suggestion try GLD.Route 66,or US41

Pete
