CalSpeed LS1 Mustang goes over 140 mph on stock LS1 bottom end today @ famoso Well im still sitting here in disbelief....If you arent familar with the car ,this is on a bone stock 98' 88k mile 5.7l LS1 shortblock,
-stock casting 5.3l heads, EFI /w stock LS1 PCM, moderate camshaft (233/239), Victor JR EFI intake /w sheetmetal elbow /w 90mm throttle body, 28" M&H Slicks, 3.73 gear, th350 /w EDGE custom converter (stalls around 3k on footbrake)
I ran my car friday in the 102 degree heat and went 10.07 @ 134.9 mph...with a pretty weak 1.6 60ft leaving off idle and standing on it.
I didnt race qualifying yesterday and left my car out there in a friends pit. I showed up out there about noon today, since I didnt qualify I wasnt on the ladder to race. But they let me make a single pass even though they werent doing a open/test lane...
I put the 100 rwhp jets (125hp flywheel) in the single NX fogger. I figured ill crack off a sure thing 9 second pass and get kicked out since car isnt certed in the 9's yet.
Weather was 103 degrees, 130+ deg track temp...another horrible slow, 4000 Density Altitude day. Most faster cars were off 3-4 tenths due to greasy hot track and crazy hot.
Results:
Left on the WOT switch hard as I could , Car spun REALLY HARD for about 75 ft, peddled and short shifted 2nd gear and it hooked up and it just TRAINED out the back door to a 141mph!
Sad part....since it spun horrible and wasnt really a clean pass. It went 10.01 @ 140.2.... I was like "Are you kidding me! Im cursed to not click off a 9'sec pass in this car"
This corrects to a 9.67 @ 146 and I think its got a 9.40-9.50 in it with no changes on a great winter day in the coming months (dec/jan) and more mph because I feel it wasnt nearly as clean of a pass as it could have been.
Timeslip (which ill scan and upload tommorrow at work):
60ft - 1.617
330 - 4.326
1/8 - 6.522
mph - 112.21
1000 - 8.411
1/4 - 10.014
mph - 140.20
