Oh yeah!!!!
But does a pulley swap require the engine out??
Otherwise how do you get to the belt??

Stefan,
Pulley's are $595 each. You should only need the 2.8" which will give you 16lbs of boost. Are you interested in the tune as well or are you going to have the company that is doing the work do the computer calibration?
As for the warranty, that would be void if the dealer new what was on the SC. Good thing is that the pulley looks just like the stock one so most would never know the difference.
Thanks,
Dustin Whipple

STEFAN,
Very interesting mate! Tell Whipple they have a Fresno based car ready to go. I would like them to do the install. Thanks again, Cheers, daniel

Hello Jerry,
Just sent you an email. Whipple states quote "We have repullied and recalibrated the PCM to make 598rwhp from the stock 511rwhp (our dynojet numbers). We are working on a new system with Ford Racing that replaces the factory SC with our larger 3.3L unit. This will be available in approx. 90 days. We can do the pulley and cal change before that if required."
I wonder what the board thinks of his baseline rear well horsepower of 511? He quoted me for the pulley and reflashed PCM with labor 3k and for 87horsepower increase this is reasonable by my book. If the baseline is correct this is a good deal, I am seeing so many different numbers quoted that I am getting confused.
Now I am thinking assuming impact of warranty and most important getting through smog check to wait for 3.3L unit. I have asked Whipple for a turn key quote on 3.3L unit.
Meanwhile, thats Stefan for cutting to the chase and through the fat. Looks like we will be moving forward.
Cheers,
daniel

I think the disconnect is that they probably dynoed a brand new car at 511, whereas the 525-550 (?) were on engines that had quite a few miles on them.
Can someone verify?
A stock GT regardless of mileage will do about 550 RWHP. Lower numbers from people who are trying to sell you upgrades are always questionable as I have posted before. 511 is extremely low and I don't believe the run showing the 511 ran out to redline which is between 6,500 and 6,700 depending upon the vehicle and dyno. The last few hundred rpms add a lot of horsepower.
The only way to protect youirself is to dyno the car yourself before and after. Do not use Whipple's or Hennessey's dyno pre and post. Its to their advantage to keep numbers low on the pre pull. Hennessey has had a history of major problems, especially with Vipers. AUtoweek a few years ago had a major write-up about the Hennessey issues.
Also see if the vendor will refund your money if the numbers aren't improved as much as they claim. It they won't stand by their work, like Lingenfelter does with Vettes, why use them as they are telling you something in advnace.
Also check to see if they are using the same unit of measure meaning rear wheel (RW) numbers pre and post and not crank numbers which are substantially higher. I think Whipple uses crank numbers for post installation results. 550 rwhp equates to 647 crank/flywheel hp using a 15% loss factor, if 12.5% loss it converts to 629 crank hp. Thus claims of getting 700 HP really means something like a 40-45 rwhp increase. You can get close to that with a pulley change and gutted cats for thousands less than Whipple will charge.
I tried this approach with my C5 Z06 at Carlisle 2 years ago and none of the exhaust vendors or intake guys would agree to refund my money and re-install the stock components if the independent dyno on site didn't show the claimed imporvement. So I saved myself a bunch of money and am happy.

Thanks Dave!
This is good advise for all.
I have ordered the "off highway" headers from Ford. I am going to dyno before and after then consider a pulley. Using the stock muffler system, I am hoping for an improved sound but not toooo loud.
Who is a good sourse for plug in "Cat Foolers"?
I am shy about a re-flash this early in the warrantee period.

Any decent speed shop should be able to get the resistor and do it for you. It is a rather routine deal because of all the guys that gut the cats and need to pass emission testing.
If you can't find one let me know.
I would think you would get a greater HP increase than with gutting the cats. While gutting helps its not the same as eliminating.
I will not ask about emissions testng.

Hello Dave,
Thanks for your post, all excellent ideas. I am interested in the new 3.3L Whipple charger, a final price is not available.
I will watch them dyno my car in, any suggestions on what kind of a pull you would do going in and out? 1st., 2nd., and 3rd gear, 1st. through 4th.?
The say they are 60-90 days out from install. Here is a message I just received from the principal:-

Daniel,
Preliminary power levels are reaching 650rwhp pretty conservatively.

All comments are welcome, some of you folks have amazing knowledge and
I appreciate the education I am getting from you.

As to on the dyno I don't think it makes a difference if its 3rd or 4th. Typically people tell you 4th but I did both with no real difference.
Also depending upon the MPH limit of the dyno 3rd may become your only option, but they should be able to tell you that in advance. That is why I started with 3rd as the first dyno I did then had a limit of 180 mph.
If its really 650 rwhp the cost is then the next factor to consider, as you understand. A pulley and gutted cats provides 575 - 580 RWHP +/-. The pulley and cats can be done for $ 4,000 or so.
As previously posted my mods and a reflash did 10.85 in the 1/4 mile. How many other cars out there are that fast?
So what is the additional HP worth to you? Only you can make that decision.
Good luck and let us know what happens. Yes their website also mentions the delay I wonder if they are having development/install issues.
Dave
PS: Don't forget the pre mod dyno somewhere other than Whipple. Also ask Whipple for a pre and post dyno. Then re-dyno at the private dyno after you get the car back. You get an unbiased idea of what the mods did for the car.

"Vee don't need no stinking cats!"
I have a set of Corvette "Cat foolers", I wonder if the electronic values are the same?

I would be carefull installing anything on your GT whiles it under warranty because if anything goes wrong your going to eat it. My friends GT is at the dealer right now with a blown motor and the cost to replace $35K. His will be covered under warranty if it had a different Blower on it he would eat the $35K. I have a 04 Lightning Pickup and whipple makes a upgraded charger for it, but the guys on the Lightning Forum say don't do it unless your going to make other engine mods meaning internals. If your Drunk with Money and don't care about cost or replacment then by all means do it. I know Whipple built the OEM charger for the GT but its a crap shoot.
