Gen V Whipple Build - Your Feedback Please

[Logan@Lethal]

A lot of overkill here.

You can run twin 285's and support 1100whp.. That is more than plenty for your goals. We ran triple 465's as we were unsure of our goals (hit mid 8s @ 157 stock motor) and had a LOT left to go in terms of fueling. If you're concerned about the hat, all of our (DivX) hats are triple for this platform. You plug the port not in use.

The Ice tank is unnecessary for you as well, from what you're describing. Often an ice tank will hurt street driving more than help.. AKA when not icing it (I run one... so did our shop car)..

Those springs are a hard no. I'll get you a set of springs you'd like if you have some time.

What about wheel/tire?

We are Whipple HQ here at Lethal and would love to help out. We have countless customers in the 8s and below running our fuel systems and going off our assistance. Give me a shout and we'll go over everything.

Thank-you for your feedback, I have followed a bunch of your builds and I am familiar with you as well during my time with my F1A C7Z.

Wheel tire will be a simple Weld 17" rear setup on ET street R's and skinnies in the front. I hear you about the PNR chiller - but I have some experience here maintaining it for street driving - I don't know how I can maintain pump case tunes without it - and I will be on pump most of the time. For fuel - also a good point - and why I asked. I am looking at other combinations with my Shop - but it keeps coming back to (almost) never enough fuel having come from a triple setup with mechanical pump on my GTR running E98. The truth is - if history repeats itself - I will end up going all out - but as I am more seasoned now - at this moment, I happy to see how much I like the car with my stage one limits. With all of the good work your Shop, Lund, PBD and others have done with the Whipple setups, it seems that it is just a matter of deciding if I want the additional headaches. Right now - the answer is no - but I like over-engineering.

I am very interested in your feedback on the suspension. I wanted something still streetable - but that would take care of the hop and give me nice, straight, clean runs. What is it about this setup that you gave it a hard no - and what do you recommend?

I very-much appreciate your feedback.

Edit: One more question; for 93-94 pump gas - only - are 9's at 140+ doable in your experience? Is it razors edge? With the additional fuel and cooler, does that help for the random batches of fuel you will end up getting?

I'm going to send you a message so we can keep track of the conversation.

I love BMR products, but the drag springs are a no go for trunk tank cars.

750whp-775whp absolute max (probably even throwing a tad of boostane in) its very much so doable to touch 9s. You can drop some weight off the car to help, too, if warranted.

Lund has done high 9s on 93 and boostane with 3.875 pulley and stock lower balancer

Thank-you TX-R - as a Tuner yourself, is real life that if I want to drive around straight 94 octane (Canadian fuel is 10% ethanol) - that I will likely be stuck at low 10's at 138.5ish MPH? Being honest - that is fine - I just want to know if anything above 10 psi is possible (or a good idea) without the octane boost to the pump fuel.

Thanks again for your feedback - it is appreciated!

 

[TX-Ripper]

Your not going 9s 10 psi and 93octane alone

Understood. The reason I am using 10 psi is because that seems to be the limit before people start to add booster to their fuel. That said - some of the people stuck t 10 psi don't have a chiller or bogger fuel systems - so I am wondering whether with the chiller and fuel system 12 psi is possible within the fuel additives.

chiller might help, bigger fuels system will not help or hurt as its just there to support larger fuel volume needed by ethanol fuels

Thanks TX-R - do you know of the highest boost/pulley setup on pump - no additive - being used these days on the Gen V builds - and what they have run?

If your going to use Lund (the best in the business) 3.875 - low 10s

if your running Whipple tune 3.75 mid 10s

I can’t find where any have really worked towards this goal because ethanol is such easy, safe, and cheap power. Increasing the gdi pump to maximize gdi blend should allow 1 more psi. A Killer Chiller should allow 2-3 more. Headers should help as well. All in all, I think 15 or so psi is possible on 93 but the tune had better be right and configured to take full advantage of the KC and Gdi pump.

Thanks TX-R - that is what I have been seeing. 10.2's at 138+. That's enough. I have no issue running E all the time - but its nice to know that it will still have something for a test and tune day. I am fortunate to say that Lund is the Tuner for my car.

I agree with you that ethanol makes people not even look at pump gas. On the note of pump - even though I have ready access to it - we don't have pumps at our stations here for E85 - so it's more of a headache. I don't think I will go as high as 15 psi on pump - but I am hoping for 12-13 safely. Lund is my Tuner - so I am banking on their experience here.

 

[engineermike]

I’ll be interested to hear lund’s feedback on 93 octane, performance, and boost.

And I will post it on my build thread once it begins.
