I like posting pics, I promise you see some. I am kinda of a perfectionist, so I gotta make sure its right first.

An intercooler in my opinion is not needed and here's why. The Twin screw that whipple makes runs a lot cooler than the roots blower (TVS/maggie), probably around 50-70 degrees cooler. Tuned a 5psi 112 maggie with intercooler and IAT jumped from 120's to 175 after 1 WOT pull in 85 degree weather. The same conditions I have not personally tested but I have heard 10-20 degress above ambient with intercooler after WOT pull.

Whipple superchargers tend not to even need intercoolers until making over 7psi. So take the 2.9 that me and BBK are going to run (we both running the 3.5 upper pulley/7.5 crank pulley) should make around 650-700rwhp easy with that pulley setup. Depending on engine efficiency that is probably around 12-15psi on my setup. I am running twin 14GPH nozzles using a mixture of meth and water so once in boost, say at 7psi both nozzles begin to spray and keep the intake charge cool. When not in boost no need to even have an intercooler, its the best of both worlds, plus you will gain a little power not having a crappy intercooler anyways due to restriction .

I am actually from the camp of just running pure meth, but the problem lies that pure meth on twin 14gph nozzles would swing the fuel mixture two FULL AFR points. I tend to shoot for 11.5 on PD blowers don't want that making 13.5 from a meth failure. A 50/50 mixture will only swing it 1 full point and take less meth, plus In the ECU I can tune it to add fuel with increased IAT's and to pull timing, so making this thing safe even with a meth failure wouldn't be an issue.

IF someone still wanted to run an intercooler I know on my manifold you wouldn't need an additional 1.5, however it depends on the size of the intercooler you wanted to use. I can close the hood on my setup (LS1 WS6 front end conversion) and I have about 1 inch of clearence between the pulley and hood without any k-member spacers. I was going to use 1/2 aluminum flat bar, but it wasn't needed. The 3.4 whipple is roughly 1 inch taller and about 1 inch wider, kinda of wish I went that route now.
Sorry to blab so much, I start a thread soon

 

when can I BUY one????

 

This is very cool. I look foreward to more info.

awesome job BBK... ill def keep an eye out for this, since i plan on starting my build this summer.. whole care is tore completely appart already, just got to start from the ground up.. im glad to be back on the forums again, its been to long guys

 

Any progress? Definatley interested in this setup if its made available to the public. Already have the motor built for it

 

i want this, i just got done a top end swap but would definetley change my whole setup for this if my bank account would let me =(

 

Updates needed

 

In for up date and possible price.

 

Getting close five months ago

 

Im not the original poster, but he inspired me to build my own kit.

Took these on my phone, so quality is not the greatest, going to powdercoat next and finishing up on a few odds and ends. I will start a thread when its complete.

Quick specs is a 2.9 Whipple with 3.5 BP and 7.5 crank pulley, everything converted over to an 8 rib system. I built the custom 3/8 aluminum bracket and installed a HD 8 rib spring loaded tensioner (looks sick on the engine)
Running a 4.5 in inlet with a card style MAF. NO intercooler, running twin 14gph meth nozzles with a 50/50 mixture. I will probably scale the MAf instead of tune it 2 bar SD Everything I fabbed including the base plate which started out as a SBC single plane, IAT built into the base. Running a monoblade TB and if you notice the valvecover on the driverside is shorter than the passenger (looks pretty sick with the tubing running right over it.

 

thats awesome!!

 

I wish whipple would have came threw with there idea, very cool build,thats alot of hard work in this build,i think alot of people are over looking that due to all the (i want comments) but if this is something you will be selling there is for sure a market,as long as its a competitive price you will do pretty well with it,again very killer build

 

I agree with above, people have been asking for more info for months... how long could this possibly take..i have been laughing that this thread is still treading water.

 

Has the curse of "innovative LT1 design" struck again?

 

I'm surprised that will clear the power brake booster.

 

bump- curious where this is at in terms of final completion?



found this on his page...

 

Mine is a close fit too, but it all fits. Just did my last test fit, going on the car VERY SOON.

 

Maybe he decided to upgrade it to the 4.0 whipple


Updates???????????

 

Love that manifold, it could be so easy with one of those. What a fantastic setup.
