NSFW Posted December 2, 2010 Share Posted December 2, 2010 I'm really looking forward to seeing how these do in practice. The 7670 looks like it should have top-end power pretty similar to an ATP 3076, maybe a little more. The thing I'm most curious about is what RPM it hits 20psi. I get that right around 4000 in pulls on the street, and the hype says these turbos will get there sooner... but how much sooner? Not that 20psi is really special, but 20psi @ 4000 is just a very common and easy-to-remember data point for 3076-sized turbos. And of course, there's also the question of how Garrett's corresponding GTX turbos perform... interesting times ahead. Link to comment Share on other sites More sharing options...

What I want to see is the difference in hitting 20 psi in the lower gears, that is where the lower mass should really come into play. What rpm does your 3076 see 20 psi in 2nd gear?

Legend Posted December 2, 2010 Share Posted December 2, 2010 What I want to see is the difference in hitting 20 psi in the lower gears, that is where the lower mass should really come into play. What rpm does your 3076 see 20 psi in 2nd gear? Guys I like the "20psi in 2nd" number too... since everyone runs different peaks it's nice to have a standard for comparision and glad I'm not the only one who is concerned with boost in 1st-2nd. For reference, my BNR68 hits 20psi in 2nd by 3900rpms and 1st by 5300rpms. My '05 LGT My '07 Supercharged Shelby Link to comment Share on other sites More sharing options...
Hops Posted December 2, 2010 Share Posted December 2, 2010 -elevation -gas you plan on using -what intercooler -how are you doing the intake -what other mods 7670, huh? I'll look into that one, too. I'm looking to hit about 400 whp with an excellent powerband. -elevation: 4200+ -gas you plan on using: E85 -what intercooler: Cobb -how are you doing the intake: custom -what other mods: 1000cc top feed injectors, tgv deletes, fp, and all the regular goodies.

Hops Posted December 2, 2010 Share Posted December 2, 2010 I'll probably flip the intake manifold to reduce intercooler piping, which will have to be custom made as well. Buy my cars! Link to comment Share on other sites More sharing options...

You'll need at least dual pumps.

Hops Posted December 2, 2010 Share Posted December 2, 2010 As far as I know my 255 is good enough. If I wanted more like 500 whp I think I'd need dual. Buy my cars! Link to comment Share on other sites More sharing options...
Th3Franz Posted December 2, 2010 Share Posted December 2, 2010 E85 needs a lot of fuel, even at altitude. A single walbro was cutting it too close on my friends 400 whp E85 STI. He has 2 in-line pumps with an intank pump with a surge tank now. Plenty of flow for future goals down the road and a nice margin of safety. -Franz The end of a Legacy http://www.youtube.com/th3franz Link to comment Share on other sites More sharing options...
mattg Posted December 2, 2010 Share Posted December 2, 2010 One of the new DW pumps might be the way to go. Don't they flow over 300lph? Link to comment Share on other sites More sharing options...
Hops Posted December 2, 2010 Share Posted December 2, 2010 They're 300. I think that's the next step for me before I go dual. Buy my cars! Link to comment Share on other sites More sharing options...
mwiener2 Posted December 2, 2010 Share Posted December 2, 2010 on e85, at altitude, at 430hp, I have no issues with a single walbro 255l/h with 1000cc injectors, you'll run out of injector before you run out of pump My Mods List (Updated 8/22/17) 2005 Outback FMT Running on Electrons Link to comment Share on other sites More sharing options...
LittleBlueGT Posted December 2, 2010 Author Share Posted December 2, 2010 7064 at sea level should be enough for 400 whp on E85. If you are talking about an accurate airboy (with accurate tire measurements) at 400 whp, or a low reading Mustang (not COBB, not EFI, not Surgeline, but like old PDX) then I do think that you will need more then a 255 pump. 300 lph pump should work (I have yet to see a review on the new DW one), but I wonder how the 1000 cc injectors will work? I think you may run out there too, and might need to up the fuel pressure a bit. Sounds good to me! Full tune of 68HTA, KSTech 73 MAF, Racer X FMIC and ID1000s................by the DataLog Mafia!!!

Hops Posted December 2, 2010 Share Posted December 2, 2010 I'm working with Cobb's tuner at the moment and he says we should be good to go, so we'll see. It's still a couple months out, but I'll probably start a new thread on the build. We'll be tuning on a Mustang dyno. Anybody else going EFR yet? Buy my cars!
