2018 Whipple GT - Break It, Build It, Race It, Hopefully not repeat it!

[Det_Riot]

Been a Considerable amount of time since the last update but I'm glad to finally say that we have oil pressure! Seems like we fought the process every step of the way but it's finally together and finally running! While the engine was out we added a pair of LTH Headers, and upgraded to the Lethal Performance Triple Pump return system for 18+ Whipple cars in preparation for the 10-rib and all of the boost! Springs got swapped out from the standard BMR 086 drag springs to the tried and true BMR 082/089 set up to accommodate the added weight of the whipple! We've got to chase down a few small issues; leaking fuel filter because I dropped it on the fitting end and fuel not wanting to prime off the yellow/gray wire, but we're hopeful that it should be buttoned up this weekend and ready to make some steam!

Did u find out why the yellow/gray wire would not prime the pumps??I have this issue on my car.

No, that’s on the agenda of things to button up. It’s very frustrating because we had the Sai li Kit wired in the exact same way and it primed with no issue. We just jumped the fuel system off the purple wire to trigger the relays for now but we plan on going back and fixing it before we call the car dyno ready

That's odd, I had a friend with a single turbo 18 say the same, for some reason neither the yellow with gray stripe or violet wire would power up his pumps, he ended up having to use a switched 12v source instead.

I know the fuel pump inertia switch is in the fpm now.Maybe somehow that could have got triggered?Their is a reset procedure for the fpm but i am having a hard time finding it.A bunch of push button on and offs with hitting the brake pedal but not sure of the order.

So I’m messing around with the car today and still can’t come up with anything. Checked continuity to the ground off the plug and no problem, tried to check the smaller trigger wires off of the FPCM connector (BROWN/White and yellow/orange) and neither of them are getting any voltage on ignition on. Are these supposed to be trigger wires from the PCM? I looked at the wiring schematics I’ve seen and they translate back to the PCM. Idk I’m at a loss right now

Check fuse i think 48 or 49,its a red square box fuse.That sends power to fpm.

Took a little bit of time last night to finish buttoning up the car some more after our initial test drive. We threw in the towel on trying to diagnose the lack of signal from the FPDM so we just piggybacked the ignition on source that we used for the intercooler pump. Wired her up, cleaned it all up, and walla! pumps functioning as normal =D Initial impression of the Lethal Triple Pump Fuel System is outstanding. They include everything (I mean it too!) needed for install aside from the actual labor! For those who aren't familiar, they use a DivisionX Triple pump hat, walboro 276's (~455 lb/hr), and every single line needed to put the kit together. We decided to relocate the relays and inline fuses to behind the trunk side lining out of personal preference but the harness they send you has more than enough wiring to mount them where ever you please.

Felt good to be able to finally give her a bath after she'd been sitting for 3 months!

We found a 3.375 pulley laying around the shop so we threw that on it just to start getting the tune dialed in and making sure everything is straightened out with the car. With the stock balancer it should make right around 15psi. We know the engine will be capable of handling more, we just aren't sure how hard we can push the oem 6-rib set up without getting into belt slip but we're going to figure it out until we can recoop some funds for the 10-rib upgrade, then it's full send mode!

More updates to come soon, should be on the dyno this week!

Very nice.. congrats on getting it going again.

Congrats on all your hard work.
Mustang GT looks great!

Finally got out to the track after the winter rebuild! Respectable numbers coming out of the winter build up on only 14psi! Great first outing for JoAnna and the Alternative Crew! Should be able to push another 2-3 tenths out of her as it sits with some better track conditions. We weren't able to go WOT until about 10-15' out.

9.6 Strong run! That Mustang looks to have a lot more in her, also adding drag wheel & tire set up will help a lot. I see 8’s coming soon!

Nice and congrats .
What size six rib pulley ?

Thank you! The fronts were an 18x8 so not saving too much on weight, the Baer brakes should help with that for the time being! Most definitely more in it with a better short track!

Thank you sir! 3.375” car floated around 14.25 psi on the dyno

 

[olaosunt]

Do you think the 3.375 pulley is slipping ?

Sorry if I missed but what rear end ?
