Good to see you posting here Gustav! Nice ride today with only 6 psi boost, but we will first see how much hp it will make on Shell V-Power fuel@15 psi boost. Then it turns interesting...

Are you running primaries on the iron? I see you have some 1680's in the Xcessive primary ports. What are the white tops in the secondary position? They almost look like 150lb injectors as they were white/gray tops...

yep, 2x1600cc + 2x1680cc on xcessive and 2x850cc on the iron.

I understand this. For example we can use Ernie T. I believe he was using 2 X 1680's and 2 X 9xx injectors and cracked his 752 rwhp. The t78 has a smaller compressor wheel and inlet (forget the lbs/min). I think you're going to have a big problem when you have those injectors come online. The only way I can see you making it happen is to lower the fuel pressure...

As far as i know 752rwhp was on race gas? we saw almost 50% more fuel consumption on e85 on high load compared to gasoline. we ran out of 2x1680 + 2x850 injectors at 479rwhp with same turbosetup and port specs. this only at 15psi boost.

And hey, if it doesn't work good ill put 2x850 insted of the 1600.. not a big deal..

That custom manifold looks clean. Did you fabricate it yourself? What size is the TB?

Holy cow, tip in must be touchy to tune!!

Nice setup man, should be loads of fun. And that weldon fuel pump is badass. All the whiners who complain or BOAST about the noise their walbro makes needs to listen to a REAL fuel pump for once lol.

Good work!!

I was unaware that e85 took 50% more. That's worse than c16, so maybe you'll need all that fuel

Its 33% more generally, but he said at full load (meaning the safetune is probably rich, which is good because blowing motors is no fun).

I'm in love with your throttle body.

well.. there is still only 4 bolts holding the turbo, nothing is unchangable.
479rwhp at 15psi is pretty good for this dinosaur...
