Anyone run 3.25 or smaller on a whipple

[Roh92cp]

I made 750 on straight 93. Pulled 2 degrees@7100 on the dyno, so now I mix Boostane to 100 octane. 19 degrees all the way to 7800 with that mix. That’s the tune I run all the time now. It made 880 on E, but I’ve had traction issues, so I’m not trying that yet. But that could be an option for you

How much BOOSTane do you add to what fuel 93 or 91 to make 100 octane?

I put 10 gallons of 93 in with 11oz (1/3) of a can. I just keep using that formula every time I need fuel. According to Boostane app, that’s 100 octane and according to my Ngauge and logs, it’s working

Thats great and almost what I do except I fill at about 1/4 tank which ends up being about 11 gallons. I spray meth on top of it all and get 22 spark advance 0 knock up to 8K rpm PBD calibration. I'm on a Gen 4 whipple with 3.5" pulley long tubes not cats and see 15psi.

That's the exact belt I ordered one regular and one RPM. Order the griptech too 3.25. I'm hype tho. The motor should be back in the car Wednesday/Thursday. Yeah I know is the luck of the draw too. Some peoples shit braking on 5 pass some last 50. But once I get the 10rib I'll be on 3.0/18psi and I'll throw the 2.75 on at the track to go for that 8. We will see

How much boost do you think with the 3.25 pulley ?

Should make 16psi. Leathal's car made 941/742 on 17psi. I'm thinking I will make around 915whp. Here's there setup from stock to now.

Yikes !
I think I will start with the 3.375 then .
I will keep the 3.25 as my “kill” pulley .
Hopefully it won’t kill my stock engine !

Shit they run that 17psi on a stock motor. But you know how that game goes. It could last 5 pass it could last 100 you never know. But I can tell you mine didnt last one at the track lol. I think 15psi E85 stock motor she "should" live for a while. But really for me that is playing with fire. On 15psi you should be mid 800's. I dont know. I dont like these PBL for that kind of power long term.

Did you ever get to make a pass ?

Think I will keep the 3.25 for the Shelby . ..at least that should be built for it .

It probably won’t make as much boost with the Gen 3 Whipple .

I am tired of building motors but when I recover from rebuilding Voodoo I will have L&M build that 5:2 block they have with them with the Manley I beams and DI specific pistons . I will have to figure out how to the relocate knock sensors.

I also wonder if the Gen 2 long blocks I already have (11:1 compression 5.0 and 12:1 compression 5:2) would work with the Gen 3 ECU ?

No not one pass. The ecu dont know what block is in the car. However you will need to figure out the DI side of things.

I'm use half a can to a full tank. Its making a little over 760 with no issues.

I should probably have asked in your engine rebuild thread but did anything else make you check the compression other than the oil on the plugs ?

Time to start planning a spare for this car as it’s a keeper (plan on selling the 15’s)

If I used one of my spare long blocks (Gen 2 /GT 350 heads ) why would I still have to worry about the DI?
Could I not just run a tune for a Gen 2 ?

Please consider I am tech disabled in your response if that’s a stupid question (I need to have that disclaimer on all my questions. Lol)

Compression in 3 cylinder were 180 and 7 was 120. Ih I got a pick of your block today lol. As far as running a diffrent tune out if my wheel house. Message lund.

 

[olaosunt]

Thanks for the pics man .

Plan is have them rebuild it once I recover a little .

It will require 3.71 bore custom pistons and should be stout with the I beams although they said they don’t recommend that big a bore with F1. I will still send it if I build it cause I am a boost junkie !

May be I can sell it to one of the NA/track guys looking to covert their Voodooo to CP ?


I know you are tired of my stupid questions by now but I was asking WHY you did the compression test ?(NOT which cylinders were low)
lol

 

[PC 2015]

Oh why did I? At the time did know what it was I just remembered the little bit of oil on cylinder 7 so we checked. No stupid question your good

 

[olaosunt]

Thanks again man .
Last question.
How are the knock sensors located differently on the Gen 3 block compared to the Gen 2 ?
