Whipple numbers Stock

Yes we did. Their tune made 700rwhp on our car right out of the box with the larger TB option.

What size pulley? Was it the standard that came with the kit?

most racing actually happens from about 6300+

here is a graph from one of our 9 second runs.

the graph starts where I launch the car foot braking it, so this is from a complete stop,

just under 1 second into the run, you can see the rpms are already at 6223 rpms.. that's less than 1 second from a complete stop.

a roll would be even less, and , this is an auto car with 4 gears to 1 to 1, a manual has 5, so the gears are even tighter and would be less time.

on the shift, the car never drops below 6300 rpms... 6300........................

our vortech car, and the prochargers, make peak torque, closer to where it's needed for a run.

if your racing, 95% of what you need is from 6000+ those are just the facts with racing.

We used the standard pulley which came in the kit. I don't recall the actual size of it but I believe it was either a 3.50 or a 3.75".

Nice! was that 12 psi?

Boost was anywhere between 10.95-11.88 with that pulley.

The OP is not racing his car. He has stated this so he is not asking about racing conditions.

If your goal is the most power at light throttle from 1500-3500, (like from a stop light to 40) then a pd will get that goal for you better

but if that's a case, then peak #'s on a dyno really aren't important either, as you'll never see those rpms

100% stock vehicle, 350 miles on it, testing today, 108.4deg F in the dyno room since Fresno is like the Sahara desert today. Don't mind the dip at tip in, got some wheel slip. Take a look at the boost curve.

I would love to see 4 pulls and the IATs at the end with a 108.4 ambient.

Seriously, not poking. I think that data would be beneficial.

Which throttle body was this with?

Anything new in the works for the manual tune? also the manual w/headers?

 

[BOSS 32V]

OP, the whipple will accomplish your goal, driveability will be just like stock, you'll be impressed by how well this kit is put together and the looks of it.

Next week on the LT based cal. We've made some updates this week on the manual and more updates next week. Monday is the official release of the new high rpm auto cal, with updated shift logic.

Any chance we will see a tune that will be a little more aggressive on the torque side?

 

[gsxr1300]

Nice! my PCM should be on its way to you as we speak.

At this point we don't feel it would be safe knowing all the factors that must be included in a cal we release but we are always learning/updating/changing so I can never say never. We have more testing then almost anyone, thousands of hours at 0 to 120 deg f, at part throttle, wot and steady state. The calibration optimizes timing and air fuel depending on all conditions, giving the motor what it knows is safe but at max. We use factory tools in factory conditions with Ford calibrators.

We tested many different cam timing combos (even simulated using the same OEM program used to design cams), boost levels, air fuels and almost everything else possible. You can see our boost curve, we have one of the flattest curves offered on the 5.0. After all the testing, including isolated environmental chambers as well as real world conditions, we feel this is max on pump gas on stock engines. We did verify that we can run slightly more boost which nets 20trq/hp more but that's optional for customers.

Because we have the boost, timing, IAT2 and air fuel optimized, the only real way to make more torque is cylinder pressure. With cam timing, you can increase cylinder pressure, but we found that while that makes more power on a quick swept test, it severely detonated in real world conditions. In fact, during knock calibration the stock knock settings couldn't even detect it because it was so far out of the thresholds. We worked with a knock cal engineer on actually detecting actual, real and false knock. We have timing optimized per cylinder as well as knock and that's how we get to the power we quote with incredible durability. We actually lower the actual compression in the engine to run more boost and safe timing/afr which we feel is optimized.

Custom tuners such as Lund and others may find some different results and possibly optimize a cal for a persons given application and environment. We will continue to look into optimizing power along with continuing to bring out new products.
