GT/SC Cars - Whipple vs. Paxton

Recommended Posts

I have noticed that most folks really, really, really like the shock tower to shock tower Ford Racing brace on the SGT (as do I). Those who bought or are considering putting the S/C on their car mention that brace a lot. Would Paxton people opt for the Whipple if there was a brace as cool as the Ford Racing brace that fit on the Whipple equipped cars? I am getting the Whipple when my turn comes up at the Mod Shop and I am considering having a custom brace fabricated. Has anyone seen a custom one out there? It would seem like the GT500 people would flock to that. Jim

As Ghetto as this sounds,I've been told that a couple of washers under the brace will allow it to stay with the whipple style charger.Don't know for sure but it doesn't sound like a good idea.Check with Lethal performance thought I heard they had something like you are talking about.

I like my SGT strut tower brace, but if it had to go away for the sake of performance, it would be gone.

 

Truth is, I like the Paxton/Novi centrifugal option over the Roots/twin screw style Whipple.

 

I have explained my reasoning here in other threads, and there is a a lot more to consider than just the value of the strut tower brace.

 

Pick the kit you want for the reasons you want, strut tower brace aside. Then do what you gotta do...

Jim, I have researched this to death. There is currently NO brace that fits over the Whipple with the stock or CS hood option. There is a Roush brace that is used that Dave C. posted awhile a ago but the height of the Whipple vs. the Roush allows no room. The only option I have come up with is a 8 point tie in. 2 to the firewall then 2 to the strut towers. A monte carlo bar as in the 60's Shelbys to tie the 2 fenders together and then run from the strut towers to the monte carlo bar. Here is a photo but there is not current application for the SN197 platform.

I realizie that Amy stated that the hood on the new Terlingua would not be sold seperately but it has a 3" higher draw and is functional. Icould very happy with that hood and then the strut tower brace options become many. :)

 

Can some Photoshop expert put the Terlingua hood with the yellow paint and rabbit on a black SGT with silver stripes? I want to see what that looks like before I order one. LOL

Adam,

Does the KR hood give us more clearance ? I think I like the KR hood better than the Terlingua hood. Need to see better pictures though. Rick

I love the KR hood but I don't think it would work on the SGT. Since the fascia is different on the GT500, I think it wouldn't line up. Either way, I don't think it's an option, I was just dreaming. Plus, I love what I already have.

Check out this strut tower brace. http://www.stangsunleashed.com/photos/p17_...17_imageid/1390

Look like a Whipple will fit under that.

 

It sure does,Wonder if the Bullitt hood is a little different?If not you guys may have just found your answer,If it will be sold seperately.Looks like it's made out of aluminum,Surely not.

Oh crap :wacko: Another tough choice to make. I'm selling my 67 Mustang trying to raise money to ship my Shelby GT back for a Super Charger. I was all set on the Whipple, now I learn you can't have a strut tower brace with it. Does any one have real world performance data between the two? HP numbers don't all ways tell the real story.

Correct the KR and the SS hood will NOT fit on our cars. Of course I asked John and Bud this a few months ago. Also there is NO room for any kind of strut tower brace if it goes over the Whipple that you can use the CS6/CS8/GT-H hood with...again I asked about that as well. I am having something painted on the underside of my GT-H hood and there is just enough clearance for it not to get rubbed off.

 

:blink:

 

Sorry Jim. You are in the same boat I was/am in but I can tell you it is worth it. I drove my car for the first time today with the Whipple and it is AWESOME. The low end torque is exactly what I hoped for and was constantly pushing. I couldn't drive it too long before the pain started bothering me but it was worth it!

 

:D

+1 I'm very happy with my Whipple the low end is very fun :)

I currently have a centrifugal in my 96GT (Vortech). It's ok, but I definitely want to go with the Whipple twin screw route this time around. Heard nothing but praise for this S/C. I too don't like not having the strut tower. Oh well.

 

 

Are you running an intercooler with your Vortech? What did they estimate the HP at. I would really like to find some real world performance data between the two? HP numbers don't all ways tell the real story.

No intercooler. My Hp on a mustang dyno was like 235rwhp, which equates to about 267rwhp and 304rwtq on dynojet. I didn't do a stock pull but typical results for 96GT were in the 180rwhp range (so about 87rhwp gain over stock). I don't have any 1/4 mile results. They would be bad anyway as I have a very tough time hooking up and just end up smoking the tires (think it my lowered springs and koni shock setup)

On the bottom of page 22 in the winter catalog there is picture of the Terlingua car. Under it says look for parts from the Terlingua car begining in the Spring of 2008. Included in the descriptions is the deep draw hood.

 

Thanks!I thought I saw it in the catalog but couldn't again last night!

....I have the Paxton (Vortech) Novi 1200 with an intercooler. On 91 Octane on a 90 degree day the car put down 441 RWHP and 399 RW Tq. Others are getting a bit more or less depending on tunes. I think the highest I have seen is 485 RWHp.

Also could you add how noisy the Whipple is compared to the Paxton.

 

 

The Whipple is silent unless you're leaning on it and then its a pretty subdued whine. I see in my recent autoweek an 06 GT with the Whipple is for sale claiming it was the 07 Cannon ball run winner.

Thanks socaljafo, That's what I'm talking about. Is yours a stock Shelby tune or did you have someone tweak it? How noisy is the blower. I drove a Harley Truck with the factory blower and it was louder than the exhaust.

 

 

...sitting at an idle you can hear the gears turning. Under boost you can hear the rushing air. Rather cool but not obtrusive. Certainly not close to being as loud as the exhaust.

 

I had mine retuned on a dyno by a local Mustang performance shop.

Hi Chris,

 

Curious why you had it retuned. Did you drive it a while and feel something was lacking or did you just want to play with it a bit? Thanks. Jim

I can't speak for socaljafo, but in general , the out of the box tunes are pretty vanilla.....car will run fine, but not optimized for climate/alt/ other mods on vehicle/vehicle nuances.

 

when I did my sai sc, ( added full length headers/hi flo cats) my custom tune picked up another 43 rwhp

see before/after tune results below ( sai/paxton supercharger tune vs custom)
