On our KPM dyno the results above equate to seeing many vehicles running lean at middle to top end with a 1 pump set up. This is the primary reason we have developed our Streetfighter Twin Intank Pump Module system. Along with our KPM1000cc/KPM2000cc Injectors,it is a once only solution if you are upgrading to any higher power level, with the ability to run continuous 750kw on Petrol and 600kw on E85.get an adjustable fpr and crank the pressure to 50 psi or so. 044 will laugh at it no probs. also as said the pump should be receiving 14v or thereabouts at idle. an extra pump would still be a good idea though I recon. u should see how much fuel jap cars need to make 400kw on e85 its ridiculous.

I had no idea they ran that much fuel pressure standard. typically its 36psi at idle. normal. but not in these beasts. u wouldnt think standard fuel pumps were too bad holding up to that amount pressure though would ya ? and imo I would not touch the standard reg mate stock is perfect if they are running 4 bar !! u would never need to go higher than that on a street car so if u got an after market one u would still keep it at 4 bar lol would be throwing money away.
