well i went to the track with the car and on my 1st pass i missed 2nd 3rd and ran12.8@129 2nd pass missed 2nd started to brake up up top so i let of 11.8@131
3rd pass read the log whent lean so i turn the boost down to around 23 lbs (dam duty cycle) log read 25lbs and missed 2nd and granny shifted 3rd and 4th ran 11.3 @137
then fighting with the clucth adjustment (thought that was what was wrong) went out again and missed 2nd granny shifting and the broke 3rd 15.1 @91.

so took out the tranny last night and found the shifter nylon broken ( brand new) that was my problem the whole time so when i took it apart i just broke the 3-4 fork

but as far as the fuel you ever use magnafuel pumps i was looking at the mp-4703

better to be to big than not big enough

Yes that pump will work. However it is overkill for your set up. Not to mention it is $724 from jegs. You always want to get parts for your car that you can grow into. You do not want to get parts that you are never going to use. You said your car made 555whp with the old set up. with the new set up at high boost I would say you might make 615-645. let say next year you upgrade to a bigger turbo and do some other work and you get up to 700 whp. that is still only 770-800 at the flywheel. You do not need to have 1500hp worth of fuel to make 800. I would buy a fuel pump that will handle 1000hp at the most. this will allow enough extra fuel just incase and you will probably save around $300 on the smaller pump.

hey dan

i'm makeing 641whp now on the set up i have at 30lbs. i'm runing e85 so i need about 30% more than on gas. but my setup should handle about 42-45 lbs and i will be there as soon as i get a pump. I also plan on upgrading to a bullseye's turbo in the next year, with a new exhaust manifold. Then try to put down the 4 digit HP number

Just so you know the cars in my class run 8.70 @170+ mph the average time is 9.0 at 160's mhp

so i need more power alot more power. and just what 1 pump

I guess you need a big as pump than. Why again dont you look into a mechanical pump? I am a huge fan of Mechanical pumps and dry sump oil systems!
