anyone have a Whipple?

[Dave B.]

well im getting a whipple and wanted to see if anyone have a 17 Lbs pulley one one and had any issues with the stock fuel pump?

Iv been round and round with this question, some say I have to change both the fuel pump and injectors, then some say just the injectors, then some say i can make 600 RWHP with just changing the injectors, geez,

I would like to hear from someone that actualy has one

I can tell you that when you get upwards of the 550+ mark, you never want to run out of fuel. If it were me, the least I would is the injectors, focus or GT pumps, and a boost-a-pump from Kenne Bell....if it were me, id do like I did and go return style, but it's not cheap...but i wont run out of fuel til the 1200rwhp mark

[Dave B.]

what about racing seats?? I need to get farther back a few inches and no one has those rail extenders, the company that made them is out of business,
so my other option is to buy some Corbeau CR1's they go back farther and im hoping to get about an inch lower in the seat,

anyone have these??? talk to me!!

[InfamousSVT]

The absolute minimum you can do for the fuel system is 60lbs injectors and the KB BAP. I would recommend getting the upgraded fuel pumps. www.lethalperformance.com has a great deal on pumps and they also have the Aviator or Ford GT fuel pumps (comparable to the 255lph pumps).


For the seat extenders try here: http://www.rpmoutlet.com/03cobraseat.htm

Hope that helps! Good luck

RPMOUTLET no longer carries those seat rail extentions, they were the first one I called, in fact the company that made those track extenders went out of business, I see they still have them on there web site,,,but no go

Dave, I have a 3.20" RR (15~15.5 PSI) upper, stock lower, KB BAP & stock pumps, Siemens 60#ers. My BAP is set to "15" & the FJO wideband read 11.5->11.2 A/F during WOT & a perfect 14.7 under normal cruise & idle...
I was first in line for the ATS dyno day & we had strap clearance issues (no better way to say it) & were unable to load trunk monkies to help weigh the car down to aid traction. Rick stopped the pull around 6k with the tires blowing off & I got a 575/523 printout for that aborted run...

On to this past Tuesday. First half of the day Rick was welding in full length sub-frame connectors. The second part of the day was spent swapping out my SCT chip for an XCAL2 (so I can datalog) with the same program as was in my chip & swapping on a 3" RR upper (17psi). Rick was prepared to make adjustments as necessary but here's what we found out on Ginger - your results may vary:

We crossed the straps (no clearance issue) & with KB & myself in the trunk this time (+480 lbs) the tires began blowing off earlier, around ~4k . I readjusted the straps & finally got near a full pull & then thermal overload. She laid over & Rick got off it... My fuel pump duty cycle was 100% by 5800 with the new 3" upper pulley. Done. Fin. Game over,man. Rail pressure held @39, A/F went up to 11.7 but the fuel pumps were taxed. It was late (7pm), we were all tired, and it was obvious we weren't fixing the issue(s) that night so we dropped back to the 3.2" upper (15.5psi) & tune where Ginger rocks & called it a night. Have I ever mentioned Rick's customer service is second to none?

As Ginger is daily driven, I need reliability before I need that extra power - we'll get my issue(s) resolved & I'll let you know what all we find. I'll most likely go with a custom fuel pump/delivery setup - but that'll come a little later.

What works on one car may not work on yours. Most importantly your tuner should know what to look at during/after datalogging the tuning session to make recommendations for your car. Use our comments recommendations as guidelines but trust your tuner.

I do not think you will get the numbers safely (or at all) with stock injectors... In addition to injectors a BAP, Focus/Aviator pumps, or BOTH may be required. Looks that way for my girl.

[Dave B.]

so what your saying is 15 Lbs with the OEM pump was OK but with the larger injectors, yet once you tried to go to 17 Lbs the pumps ran out of power???

Right?

I'm saying my setup for 15psi was without issue using OEM pumps, 60#ers, stock lines & rails & KB BAP(@15) Had it been able to hook, I'd made 600-610(says Rick) click for the graph...

My fuel pumps were 100% by 5800 i.e. outa fuel capacity @ 5800 with 3" upper, yes... I was making more power earlier & towards the top there was no more to be had.

As you turn the blower faster you'll need more fuel. Am I saying you will hit the wall as I did? I really don't know.

[Pro-Dyno]

The issue you are going to run in to is volume. the factory lines cannot support enough volume to keep up with more than 15# of boost. you literally suck them dry not really but close enough.

You need 60# inj and jdm style duel lines fuel system & stock pumps. with this set up it will give a range around 670rwhp boost a pump is a bandage that can fail. if you are going to spend the money on a wipple why slouch on the fuel system. as for a stand alone fuel system it comes with a huge sacrifice to drivability. these cars are set up to run with a return less fuel system. when you put in a return style the computer goes crazy because it can not control fuel pressure. if you do not think 670rwhp is not enough range use the focus pumps and you should yield around 780rwhp.

[Dave B.]

from WHipple them selves:

"Up to 600RWHP can be made so long as 42 LBS injectors are used as this is the absolut HP limit of the OEM Cobra pumps"

Now thats what Whipple says, but im just going ahead bitting the bullet, and buying the Focus pumps also, its a very very large check to write,

Whipple SC $3400
Injectors $450
Pumps $260 (pair)
labor $700
tax $336
shipping $100 (aprox)
----------------------
= $5246 (est of course)

anyone want my stock Eaton with a Billetflow 2.76 pulley and an Aux-idler??? anyone??

[blk04cobra1]

very nice mod list, Dave...and if someone over here doesnt buy the blower, I know someone on another site will

So how are you going to get all this power to hook up? If you can't catch traction whats the point in having 600+. I'm no where near that and 1st gear is all smoke on street tires and most of 2nd.

[Pro-Dyno]

some one at wipple must have type error because 42# injector’s aren’t going past 510rwhp before they are at 100% duty cycle they are rated for 600 crank and the pumps go a lot further when you increase the fuel lines to a duel line system.

DRs or slicks Otherwise, you're drifting

[Dave B.]

now see thats what I mean about this kind of stuff, everyone has a differant story, you say 42 lbs wont handle it and the tech guy at Whipple says it will, now what am I supposed to do now?? what data can you supply me to back what you say up??

they said they have data to back them up?? what say you ?
