High Mileage and a blower question

01-04-2002, 02:03 PM

This is the 2nd time i posted this...it disapeared after 30 minutes last time....I have a 94L with 126k on it. I recently upgraded from a PD putting out 10spi to an S trim putting out 14psi at 5200rpm. Base fuel is at 45-47psi at idle cruising it goes to about 50. When I stick it it goes to 80-90psi with 30lb injectors. I have an X-pipe, Flowmasters, 70mm throttlebody, MSD 6BTM, one of Sals chips. I know the fp is a little high but i chosen to leave it there as a saftey measure....better to have extra than not enough. Is the general opion that I am playing with fire with this setup/mileage or with a "safe" tune as I described am I in the safe zone? Thanks in advance!!!

Keep an eye on your plugs they'll tell wether you have to much fuel pressure.You didn't say weather you had an FMU.I run a Kenne Bell blower with 8#'s without FMU without problem, plugs look clean.

Forgot to say I have 145,000 on mine, still runs strong.

Can I ask you what pullies (crank/blower) you are running to get 14psi at 5200rpm? I am assuming you are running stock heads/cam/intake? Just curious...

Wish I had an answer to your question, but I don't.

Thanks,

BTW, where is Vinton, VA?

Yes I have a 4:1 FMU. I am using the Vortech 8 rib conversion kit with a 6.875 crank and a 2.75 blower pulley. I have an ASP 7.25 lower pulley but I am hesitant to put it on at this point as I expect I would see 16-18psi and I really dont know how well the motor would react to that. One other thing also is that this is my daily driver/playtoy as well as tow vehicle so while I want it to be peppy I cant get to crazy as I want to stay reliable everyday as well as for those 3 hour one one trips tot he track....yes I said 3 hours ONE WAY. Thunder, Vinton is part of Roanoke.

Thanks. I've been thinking about the 8-rib Renegade kit that a couple of guys here have been running. That's an 8" lower pulley and a 3.15 on the blower. I've currently got an 8-rib setup that appears to be 6.5" and 2.95. I'll probably keep the 2.95 in case I want to get greedy later with the 8" lower. But at this point, I'm thinking out loud. Thanks again for the input.

3 hours to the track? Where do you run?

Later,

When we go really racing we go to a 1/4 mile and we are right in the middle for Bristol (sucks) Rockingham (LOVE IT!!) and Virginia Motorsports Park (Only thing bad there is my luck!!) 2:45min to 3:45 drive tim to any of these. We have 2 1/8th miles withing 1 1/2 hours but my car has been running 6:20's and should pick up to 5:70-5:80....so why even bother, burn out, stage pull a gear, brakes....blah.

I am with you - 1/4 mile at a time is more fun!

Later this year I will probably be frequenting Virginia Motorsports Park.....which is a good hour and 15 minutes from me. I'll try to give you a holler...
