TVS vs centri

say that 2 identically set up cars (bolt ons, one with a roots style and one with a centrifugal SC) were to race from 0 to say 140... which car would be ahead of the other at what point in the race?

Depends on which centri

Seriously though, there are so many variables to consider it would be hard to give a definitive answer

Too vague. Which would win a race, a red car or a black car?

Whipple making 750rwhp would kill a 500rwhp p1sc car. 800rwhp Novi1500 car will kill a 500rwhp TVS2300 car.

Now equal power, depends on gearing, tuning, traction, etc.

If your talking, take 2 new cars just add the same simple bolt-ons. Then add a stock pullyed TVS 5-5.5 boost a stock pullyed V3 5-5.5 boost

IF you could get the TVS hook up it would most likely get to 60 first but the centrifugal would be going at a higher speed. If both where running the stock 5-5.5 boost I have little doubt the centrifugal would be ahead by 80 and pulling away by 100.
That's my 2c. As the only TVS i have been in a E-Force with stock pulleys and it took off fast but seem to just lvl out on power.

This should be fun. Lots of variables but I prefer centri for future flexibility.

Well thats why i said identical...go ahead and give both DR, same boost, auto and a pretty entry level centri. Obviously not trying to compare a ysi V7 to the LSA's 1900 blower or a kenne belle 4.0l to a V3.

The "little V3" (which the V3 has nothing to do with the size, you can get a V3 Si trim or a V3 YSI) makes more boost than a stock cammed L99 with headers can handle. I'm at 12 psi at 6200 Rpms and still using a restrictor and it isn't over spinning.

Nice centri setup with headers and bolt ons will be much easier to hook, especially on the street, than an equally set up PD blower car.

I was torn between ECS and Whipple. Went ECS and glad I did but I'm sure I'd be happy with a Whipple too. I like my setups to be easy to hook so I went centri.

I see, well the reason i ask if bc im l99, bolt ons with a blower cam and ls3 conv and im leaning heavily towards the vortech v3 but before i pull the trigger i was wondering if a roots style blower would fit me better (mostly roll racing, 50-60 and up) not too much drag racing. Most likely centrifugal then right?

Still really depends, I was playing with a D1sc camaro with similiar mods that I have and from a roll I pulled him pretty good. We didn't run but to about a 100mph but he never caught me, mine is a stick and he was auto. He may have run me down if we stayed in them but we didnt. I'm not saying which is better because they are both awesome just sharing my story. If we did it again it may go different, and this was with my Maggie before I switched to whipple.

Sounds like a challenge. Want to find out in a few weeks? You know where to find me. LOL

For the quarter mile, it's all about torque and the race is usually won in the first 60 in similarly powered cars. If we are talking mile runs, that centri will have the advantage. I'd put my money on the TVS for all around quickness under 800 wheel or so.

Ok thanks for all the input, so tvs still pull just as hard if not harder up top and at higher speeds? More difficult decision than i thought now

Don't need to run the mile for a centri to shine. The misinformed is hilarious.

Lol. That's a no brainer ... Black car wins every time. .
If the car spends time street driving I like the roots blower, low end torque is where the fun is at.

For reference my friends TT car making ~650rwhp raced a "700rwhp" Maggie and put bus lengths on it. I mean, it was ugly for the Maggie car.

Put a high stall on your car and the centri will own all the way through.

At mild boost, the Roots will win. 6psi all the way through the run is going to beat a centri that just sees 6psi right before shifting (and less after the shift). 6psi from a Roots blower doesn't make significantly less hp than 6psi from a centri. 12psi from a Roots blower will make way less hp than 12psi from a centri when meth is used on both. When boost gets high enough to the point of needing more octane and chemical intercooling, the centri wins big time. That's pretty plain and simple...to me anyway

I will give you the best example I know of from personal experience. My buddy and I have fairly similar cars, his centri and mine PD. I know the cars are not identical, but I believe it is a fairly good example of what you guys are debating here.

His car...
2010 Corvette GS, manual, LS3, ECS centri, cam, meth, 12lbs of boost. 744rwhp and I forget the exact torque number

My car... last year as I don't have a clean run on my new build yet.

2007 Corvette convertible, auto A6, eforce, meth , 12lbs of boost. 600 rwhp / 640 rwtq.
stock cam, stock converter

Both cars on 275 / 17 MT's. I know some will say the auto is easier to drive, but he has managed better 60 ft times than I have so that point is dead.

Best with the centri. 10.22 @ 137 60ft time 1.46

Best with PD 10.42 @ 133 60ft time 1.62

Same boost, similar weights and obviously suspensions.

Now that I have more power, and a converter I will obviously be quicker than last year. I believe both these cars are capable of high 9 second times with the right conditions.

Basically, from what I have seen and experienced, I think its a real toss up as to which type of blower is quicker, given identical setups. I have driven both and I prefer the PD for everyday fun, and the centri if I was spending more time doing highway pulls.

700 HP is a blast to drive, no matter how you achieve it.
