Notch goes 140 mph! On stock bottom end LS1 /w little jets today with a 4000 DA!
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.
Left on the WOT switch hard as I could , Car spun REALLY HARD for about 75 ft, peddled/got out of it and short shifted 2nd gear and it hooked up and it just TRAINED out the back door to a 141mph! It actually went a tenth slower than the pass on friday at the 1/8th mile...so this thing has some mid-low 9's in it when I work out the suspension to leave on the t-brake /w spray (needs to go 1.3 60 foots)
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 9.30-9.50 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...Also I plan to up the jets another 50hp after I get a couple more passes in and get the car hooking hard.
Car was about 2760 race weight /w bottle/lines/brackets etc in the car.
