Exhaust is TTI headers with 2" primaries into 3" system

Very interesting thread here!

All this learning is making me head hurt

Its all good tho

[AllKiller]

Lee, Good thats the way you learn

[AllKiller]

Yep
and biggest aint best

Street 383 - 440 = 1 3/4" tp 1 7/8"
Street strip 383 - 440 = 1 7/8 to 2"
Strip only 440 - 500 = 2" to 2 1/8"
Strip 500 - 550 2 1/8" to 2 1/4"
...and 550+ = 2 3/8"

For a race only car, i would say yes, Mine didnt work very well on the street though

after realising Ive just bought the wrong size fuel line, ive also realise that my holley blue pump @110gph is probably is bit on the wee size so was looking at holley black top 140gph

but found summits own 140gph, much cheaper, are they any good ?

The sumiit pump is just their version of a Holley pump, never heard anything bad about them.

The aeromotive is for EFI, hence the 45psi rating.

If you are pumping to much volume, more than required you will have dead head as you described. Also the pump is working harder unneccessarily, which can cause the pump to overheat or reduce life.

think I will buy the summit 140gph
they do a bargain kit with this pump but only -6 AN pipe, after what we all just said, that pipes too small to get the best out of the pump

Personally, I would not go for a kit. I prefer to order exactly what I need. The problem I find with kits is that you invariably you end up with fittings you don't need & don't have the fittings you want.
