Whipples, Pulleys, Tunes

Is there significant reasoning to wait for the larger size Whipple?

Has anybody tested the engine on just an engine dyno?

Muscle Mustangs dynoed one out of the crate at 645HP sometime in 07.

shows you the difference in dynos.

This was an engine dyno. There is also a known issue with intake cam timing on all 4 valve modulars. Muscle Mustangs found up to 9 degrees difference between motors.

The "promise" is that the yet to be released 4.0L Whipple will be more efficient than the existing 3.2L Gen 2.

Whipple continues to invest in and bring very fine products to our community and for that I applaud them! :cheers

In terms of empirical data - even documenting differences between the Gen 1 and Gen 2 Whipple, have been scarce and I wonder if we will ever have something comparing the 3.2 to the 4.0L.

That said, I think it comes down to what your intentions are for the SC. If, for example, your objective is to have a very reliable street car running on 91 octane, then I would suggest the 3.2 Gen 2 Whipple with a 19lb pulley. This config has proven over and over to be a rock solid, reliable performer.

At the other end of the decision spectrum, if your objective is to run 23 lbs of boost (likely with an Octane requirement well above 91), it is likely that the 4.0L Whipple will be the best candidate to run these pressures more efficiently than the Gen 2.

So, if your decision is at one of these two poles - or outside one end or the other, your decision may be straightforward. If however, you are somewhere between these extremes, then you might one to hold out for any empirical data that either Whipple or another GT owner chooses to publish.

But the whipple setup will make more power down low where the turbo's can't and the turbos will make more power up high sans the parasitic drag. It all comes down to what you want to do with the vehicle.

Could you clarify what you mean by down low vs up high. Thanks

What sort of numbers does the gen 2 3.2liter with a 93 octane tune see.

up high to me = 4000RPM to 7000RPM. Down low = below that point

A good average on a conservative well balanced street tune is 735 rwhp

My suggestion would depend on how much grip you want.

If you want traction in 1st gear, do a pulley/tune and switch to the Scuderia tires.

If you dont mind spinning in 1st gear and just want traction 2nd on up, do the whipple with a 19psi pulley and safe tune and still switch to the Scuderia tires.

Thanks for the comments. Since this is something I'm planning late this year I will wait and see what happens. If I can pick up a good deal on a 3.2 maybe that will cause me to jump.:biggrin

When the time is right (better be soon) I'll shoot for Whipple on 93 @ 15 pounds.

Thanks Shadowman.... what % gain is that from OEM numbers + 30-40% ???

[kumar]

why only 15 psi?

It is nice to hear from you Apples; I hope the all is well with you, your family, and your toys.

OEM 500ish RWHP
Smaller Pulley 625 approximately RWHP
Whipple = a tire shredding 725-735 RWHP (BTW the conservative boost number would be 19 PSI)

The solicited horsepower numbers to do not the transformation justice as the increased torque and how she comes alive with a Whipple is IMO extreme.

:thumbsup Thanks

 

[Black GT]

740 plus rwhp! I love the Whipple! I think I like the torque and feel of the charger more than turbos. I have a 21psi pulley, but see 19 20psi a mile high. It makes my Lambo Murci seem like a Honda Civic

 

[Black GT]

Oh and a awesome tune from Shadowman!! Thanks Shadowman you rock:cheers

 

[HOOKED ON GT]

Should be able to get on the gas a with a bit more stomp @ 15 V's 19....yes/no.
I'm not sure I want to cross it up in 3rd gear.
What's the difference between 15 and 19lbs in power/torque
Do they feel the same from 2,000 - 4,000rpm and is it all at the top the two versions?

[HOOKED ON GT]

Hi Shadowman.
Thanks.
Sounds like 19lbs is the number ...... looks like I need a new boost dial. hmmm
SM..... You got any dyno's of stock V's Whipple.
I'd love to see how the Whipple makes ass shoving power from 2,000 onwards.
The majority of the time the engine spends is in the range of between 2,000 - 4,500rpm, that's what I'll drive in.
I will only sneak past that when the time is right.

the 4.0 L will run cooler too :thumbsup
