Roush TVS vs. Whipple 2.3...thoughts?

What I'm wondering is how do you think the TVS would/will compare to the Whipple at higher boost levels, say 15+ psi? I already realize that both work well on the stock motor, but I'm wanting to get some thoughts on which one y'all think is the better huffer at high boost levels? Thanks

Ok, I can help you out here as I have a 2.3 whipple @ 16psi. AND, as luck would have it, I just installed some interceptor gauges and drove 174 miles to the track in Barona this last weekend to race on Saturday and Sunday.

So, as far as the 2.3 whipple goes, this is the facts:

I have 577 rwhp and 519rwtq---this last weekend my best et was a 6.685 @ 101.96mph in the 1/8th, which is about an 10.4X in the 1/4. I have actually ran a 10.67 in the 1/4 but that was with only a 6.81 1/8th mile ET.

This is with 281cid, stock heads, stock cams, and the 5R55S trans with a PI 3300 stall and 4.10s

The IATs on the drive down to San Diego were typically between 104 to 124 degrees. I was traveling the usual 75 mph and it was about 65 degrees outside. Coolant temp leveled off at 195 and stayed between 190-195. Trans temp leveled off at 175 and stayed pretty constant.

At the track, by adding ice into the water tank (I have in the trunk) the IATs would drop to about 82 degrees, and at the end of the run be 96 degrees.

With the 2.3 whipple, anything higher then 12 psi you will need a larger throttle body. I went with the black diamond as I am running 16psi.

If your interested on how it runs, take a look: http://videos.streetfire.net/video/S...rag_204198.htm

So that is some unbiased info on the 2.3 whipple. Now, hopefully there is someone out there that has the TVS at 16 psi that has done some datalogging that can post the same info.

I dont know why they dont. I am guessing they just dont have the drag race testing that JDM has. Thats the key here. Lots of Real world Drag Racing with his test cars.

I think I may have the fastest stock motored/trans/converter/suspension(as in control arms/swaybar)/full weight S197 out there.

For some reason these Saleen Superchargers really make the right hp/torque numbers to get these cars down the track. And like you said...www.TeamJDM.com has the knowledge to get them there with 13 lbs of boost only.

I know Nitrous Pete did alot of datalogging....maybe if he has some time he will see this post.

Thanks for the info....

Thanks Paul, I've kept up with your car alot over on s197forum, it hauls balls for sure. Thats impressive times for basically just a built bottom end. The info you posted is more of what we need to compare different setups. Info on strictly race cars doesn't help alot, but on a car that sees plenty of miles, thats whats important. I was hoping someone would post up with info almost exactly like you posted, i.e. how a blower setup works at a higher boost in real world, dd-status. Thanks!

Hopefully he will. Does he ever DD the car? As in trips longer than just to the grocery store etc? This thread has already been of good use to me and I hope it helps some others out down the road.

I'm wanting to see how these two setups compare, most importantly in DD-status, 2ndly track times, and 3rd trap speeds. Looks like we're on the right path, just need more people with the TVS and whipple to post up

I can say this in much less words, Roush Pla Bangg..POWER.
My air trmp driving 80mph for 1/2hr in 48% amb. cooler temp 68 % Now I have been data loging for 18years. Thats efficient...... 14lbs Stock all motor sus. Ect. 10.57 131 mph. NO TRICKS HERE.. As Paul and Harry both Saw No Nos !! Peace Roush All the way , OHHHH When you call you talk to someone,,, That means a lot to me
Sorry forgot Its all in the tune :) Super tuner Nitro OUT !

I say whipple all the way.

Well..to be honest...there are way more stock motored Roush TVS and Roush supercharged S197 stangs out there than Whipple. I mean, like I said...the Whipple makes some great power...but most can not turn great 1/4 mile times. Yes, we have one here now that does...but he does have work done to his car and is pushing some boost. Not knocking it...still awesome setup and my congrats for getting that car rippin!

If you want to truly compare superchargers, someone needs to bench flow them in the same conditions, on the same machine. HP numbers, track times etc all add to many variables.
