Whipple with 3.375 Pulley

[ramirj2]

I was only estimating that based off it making 793 on the 3.2 for the purposes of this discussion. Every dyno is different but I've used the same dyno since the beginning. The car made 750 on the 3.5 pulley. so roughly 20-25ish whp per psi for me. Of course it's hard to gauge any belt slip is holding a few hp back. It's right in the ball park for what it runs. At 15psi/793whp it ran mid 9s and I suspect it will go a bit faster with the new fuel system.

I broke my snout on 3.25 6rib with an ATI and I’m currently waiting an Aluminator
I’m planning to switch also to 10 rib and E85.
What’s your fuel setup?
Would twin pumps and ID1050x supply for 900whp?

I know someone selling a brand new aluminator in the crate

I am running a twin pump two 465 pumps and at 16 psi of boost my only problem is the stock rails.I know i am in the mid to high 800 whp.At that power with just one feed line and deadheading the rails i start to go a little lean at 7300 rpm.Not running out of pump,i think the stock rails become a issue at that power.

Thanks!
Are you using ID1050X?
I want 900 capable but don’t plan to go above 850 the aluminator is not sleeved and the 6R80 won’t like it any way. The bottle neck keep moving
I think I’m going to buy the Fore rails and modify

I have id1000 injectors.At 900 whp on e85 it is pushing those injectors close to the limit.I had to raise my fuel pressure some to help in the upper rpms.

I ran a 3.3" with 93 and meth for a short period with no ill effects on 6 rib belt. Went back to 3.5" for safety on stock motor.

Catless LT? What was your psi?

Stock motor Gen 2 here. Whipple Gen 3 with the 3.3 pulley on E85. Seeing about 21.75* max timing and exactly 13.8psi. I really want to try the 3.2 pulley and see what the 14.8-15psi feels like but I'm kinda nervous. Spoke to one guy who lost his head gasket after going to the 3.2 and I'm definitely not wanting to hurt the engine. Still on the 6 rib with a griptec pulley and holding perfect so far on the 3.3. Anybody else have any experience with going to the 3.2?

My buddies 19 has gen 2 3.0, 10 rib belt set up, 4.0 upper, 20%lower pulleys, long tubes, fore triple pump with id1700's, 150mm TB and CJ fender well intake. Trans done with converter. Did 876whp but at like 6k rpm, dyno guy didnt know what he was doing. Lund tuned. Hes about to put on the 3.75 and see how it does.

Once I run my Whipple Stage 2 on my 19 GT next spring and ring it out so to speak, I want to switch to E85. What fuel return systems are you guys seeing good luck with?
What pulley should I start with? I will tune with Wengerd for I owe him for always answering my questions in the past. Thanks

This is a very well thought out, and great performing system. It is what I am in the process of switching to on my car with the Whipple Stage 2, built short block, ported heads, etc.

Agree. I like everything I read about their kits. Are you going through Juggernaut?

 

[HKusp]

That's who makes the kit, so yes. That's who I bought mine from. I went with the stage 2 kit, upgraded the fuel lines and went with the twin Ti274 pumps.

Their stage 3 kit is on my holiday shopping list. Will utilize my Whipple fuel rails and going with the 274 pumps as well. Just need to decide between ID 1050x or FIC 1000 injectors.
