Still havent heard an opinion on the densos... this guy thinks a single one can support 800hp, and duals for 1400hp http://forums.corvetteforum.com/c5-f...lph-40psi.html

I actually have dual densos but only had a week or so to use them before I had engine trouble, but should be back up in the next few weeks. 402 with ported ls3 heads, pt88, so it should be a good test for any fuel system....I dont meant to jack the thread, I just think these pumps are worth taking a look at over the walbros. For the time I did get to use them, they worked great.

I made, and am currently at 823whp 877wtq with a 255 walbro w/ bap @ 17v, 100% meth, and 72lb injectors. DC is 90%. Recently swapped out the walbro for a stealth. Not tuned yet, but anything over 3k and it goes off the charts rich. New numbers soon!

2 walbro's and 80lb injectors will get you ~800rwhp on e85. I would think on race gas it would make 1000

Really? is anything else needed to accomplish this such as different lines and rails?

I want to setup a system that will handle 800hp on a supercharger running e85 if i choose so in the futur, but not sure what to get.

Would a single A1000 on 91 octane and twin pt62's support 800rwhp? Would 60lb injectors work or would 80's be needed?

whatever the replacement for the gss340 was.. i forget the 'new' number.

call new era performance thats where all of mine are from.

had a -8 feed when it was two pumps, a -10 now that its 3 pumps.

There is alot of random questions being thrown around in here.

Dual walbros with supporting fuel lines and regulator will make over 1000whp on gas and about 750 E85 safely. 80# inj will get there but takes some serious tuning I would use 96# to be absolutely sure.

Any more than that you would need 3 or MagnaFuel http://www.nastyperformance.com/shop...ing-fuel-tank/

Oh and no way in...an A1000 will make more than 800whp

I went with Lonnie's twin 340 set up and never gave it another thought.
