1.58 60ft has been my best, my friend has a similar setup and made a 1.56 60ft and he hit a 10.9

 

Good numbers man. I've considered spraying mine as well.

 

you will run some nice times ... btw what are you going to do to your fuel system..?? or did you fixed it already...??

 

Not intending to hi-jack......but

Yea, my sig is way out of date. Still have the little motor and D1sc, but I've upgraded to a 4303 magnafuel pump, fuel cell, return style regulator, etc. I've also upgraded to an 8-rib pulley set up and it makes about 22-23 psi of boost. Best run to date was at the rgv/houston meet, it went 10.46 @ 126.

Looking at the log, its got some still left in it, which I'm working on fixing right now.....

 

wats the rwhp u have ? timing ? sorry for he q's but nice f-ing times wat pulley u running , and how come ur mph is the same

 

i told you you could of done better .... and if i am not mistaken he has the same mph bcause it was running out of fuel (138% duty cycle)

 

Beautiful...

 

I stuck it on the dyno and only got to make 1 decent pull. The first pull I only went to 5000 rpm to make sure the tune looked good. It was ok, so I made some changes and pulled it to 6000. At 6000 rpm it made 700 rwhp and the tune up was still waaayyyy shitty 10.5 afr. On the next pull it fried the 2nd and 3rd gear clutch packs in the tranny. Got the tranny freshened up, but never went back to the dyno. Looking at the dyno graph the line was still moving up at a pretty steep angle. I can only think that it would have made over 800 with a good tune up and pulling it to my shift point of 6900 rpm.

Regarding the mph, I attribute it to a couple of things. One, as someone already stated I've got the 60 lb injectors operating around 140% duty cycle. Which is obviously rediculous. I can make changes to the VE table and afr does nothing. I've literally lost control of the injector. Two, my exhaust actually Y's into the stock 2 7/8" or 3" pipe for about 2 feet before it gets to the 4" transition. I have a feeling that my exhaust just can't flow enough air past a certain rpm/boost level. Three, I'm still running the stock procharger 3-core intercooler, which I think is a little restrictive at this power level. I don't think the intercooler is holding me back as much as the exhaust or injectors, but it can't be helping me either.

My current pulley configuration is a big crank pulley and a small blower pulley , and I haven't quite figured out how much timing it actually likes . I'll divulge the full combo when I'm the first D1sc Truck in the 9's w/o NAWZ (with the little motor, btw). Aw'****.....I said it. No turning back now.

 

thats possible ... i say go all out on your truck and get some after marker heads. 1 7/8 headers and dual 3 inch exhaust (let that thing bread) also fix the fuel and that will get you there easy .... show what prochargers can do lol

 

ttt...........
