I have a similar setup but 26in tire and 3600 stall stock 241 heads and LS1 intake 7.54@91. What's your 60 ft?

Jackson98Z28

Nevermind just saw it...should be running a lot better than that. Is it tuned?

Yea street tune don't know how good it is ...yea I know everyone telling me that seems its dwn with pwr I know a few guys say they run that with stall and bolt ons I don't know if its the tire the tuner said might be my trans slipping but don't really seem like its slipping idk maybe because of my loose stall

TORK?

Im gonna say it's the 28" tires and 3.23 gears. Definitely hurting you on an 1/8th mile track.

trap is bad low IMO, I would expect at least 90mph out of that setup and while the gears/tire size isn't ideal, it is not the bulk of the problem

for comparison my car runs nearly identical times with 3.42 and either 26" or 28" tire, it takes a larger difference in gearing to help much from my experience

the car should be trapping 90mph and running 7.5-7.8 as it sits on a 1.7 60ft unless something is wrong or the weather was way way beyond terrible...and that's based on my experience with a heavy car with crap aerodynamics


scan for codes, clean MAF, check o2 sensors, check plugs/wires, scan for trans slip, and go from there

sure sounds like your trans is going...

also check it for spark, could be getting knock retard or have a bad sensor

Mine did and the car ran "normal" (felt slower but you never know when that's in your head) but it was down on trap over 6mph

Imma go about changing plugs I have no codes or anything I was leaning toward the tune maybe I should go get it dyno tune what sign do I look for with the trans.... feel okay to me but not forsure

Thunder how do I check for spark do I need to hook it up to hp tuner

thunderstruck507

iTrader: (18)

HP tuners, efi live, or even a Snap On diagnostic scanner

you just want to look at your timing, PCM should be commanding 24-28* WOT and if you are getting any KR (knock retard) then you have a good place to start looking...if it's only a couple degrees you either have bad gas or a poo tune...if you have 6-9* or more being pulled you either have some horrendous fuel, a bad sensor, or whoever tuned it should not be allowed to touch your car again

thunderstruck507

I wouldn't be surprised to see that car running 93mph or more once you get it lined out. Just keep at it.

Man i hope so just when car ain't running right makes me feel like dam but I gotta to buy my buddy shop to use his snap on scanner to check that ill send u the info on what the timing doing at wot car smells a little rich but is that because I'm runing lt with bullets no cats

Its because its a race car duh! lol

i ran a 8.484 with a 3600 stall long tube headers lid and a tune forgot my mph but it was like 80-85 mph i also had crappy street tires. With a stall its gonna feel like it slips a little maybe you just need more power to accommodate that big of a stall that you have and you def need to get different gears probably 3:73 should do it, But did you get anything else for your tranni besides the stall? maybe a stage 2 or stage 3 shift kit might help you out as well. I got parts ordered now cam gears lifters valve springs so im hoping ill be in the low 7's( 1/8th mile) once its all finished and the tuner said id should get 380rwhp and 405rwtrq.

Albert ain't no dam race car that's ur Mr juice lol and mac no shift stock trans and talk with futral motorsports that sell the cam and he said it should be making 390-400 hp to the wheel

yea well if i was you id get a stage 3 shift kit to help with that stall because thats going to beef it up to help with the power but also to minimize the stress that your stall does on the tranni. The 4L60E that im assuming you have usually breaks down quickly after you do any upgrades to the motor I know mine did so thats why when it did i got a 3600 stall and stage 2 shift kit. Hope this helps out.
