Question PD vs Centrifugal for roll racing

Hey guys. I understand that this is a dead horse and that I should choose one that I like better, but I'm really looking for first person experience specifically on the 6th gen. This will be a daily driver for now and want to turn into a monster later. Currently my top choices are the Whipple 2.9 or the Procharger F1A. Also the TVS 2650 when it comes out. All help is welcome. Thanks!

I’m personally going twin turbo when hellion releases their kit. I like being different. Did I mention that the sound of spooling turbos is intoxicating? Lol

PD is awesome for AWD, you will fight low speed traction with RWD. Hell, with my small BB turbos, I scramble for traction when they spool. If you want big power, turbo or centrifugal is the way to go. Just look at the forced induction thread.

Most of the fast track times I have seen reported here are running Magnuson. The heartbeat setup can get you trap speeds into the 130's pretty easy.

That being said, I do think the F1A is top dawg but it's not worth it unless you plan n building the motor to utilize it's true potential. The problem I see with the P1 and D1 on the manual cars is they fall out of power on shift. The A8 should be better with a Centri.

I stated the F1A was a different animal. You need a set of drop in pistons to utilize it. I also expect the Eaton 2650 to easily do the same thing with a built motor. Today's PD blower technology has closed the gap with Centri.

What is your idea of fast ?

ALL the fastest gen6 cars run Procharger's

There are so many factors that could effect this. Are you talking about quick freeway hit roll racing? Half mile roll racing? Are you building the motor? Etc etc.

PS: Anyone that says a PD blower will have traction issues isn't running a proper tire set-up etc. A properly pullied Centri will have plenty off the hit as well.

The generalities thrown around never stop. Remember that with PD blowers the torque is instant, neck snapping, or some other ridiculous descriptor.

Ok since there is a lot of confusion on my goals. I will be eventually doing a TSP 416 with forged everything. I will also have a set of slicks/radials for balls out runs. Never doing drag, not my thing. Going for long highway pulls as shown on speedfx and runway runs. Might take it to thunderhill and sonoma and maybe even laguna seca before I go 750whp+. Looking to get blower first then build up motor. Also on the turbo idea. I have owned turbo cars and the high entrance cost and my already purchased mods wont work. More interested in supercharged applications. Car is a 2018 SS 1LE so also a manual...

Biased here because I haven't driven a centri but I understand how they say how the centri drives like a stock car until you get on it. My PD drives like I went to a bigger motor. Just raw power all the time. Just need to adjust your foot compression. But I must say I smile every time I drive the car vs just every time I get on the car. Keep in mind I'm not driving in heavy traffic day in and day out and I have my diesel truck (still has power ) when it rains or weather is cold. Mainly due to the 1LE R compound tires though. Regardless of your choice it's a great problem to have.

I "THINK" you need to look at what you are really asking vs reality. Building a drag car is easy it has one job, so it can be great at that job. Building a 1/2+ mile car is easy it has one job. Building a street car that can do many things WELL is easy. How often will the car spend doing "highway pull"? Look at the positives and negative of both systems. I think IATs are the usual issue when doing long pulls with any setup. Going forged bottom end? Really you are going to get peoples personal opinions but in all reality you have to look at the power created in the range you will be racing. F1A or vs TVS 2600 vs 2.9 Whipple really at the same power level the race will be close. Probably come down to transmission type, and vehicle weight.

That I can understand. My car is "stock like" until I get in the throttle, and after that ish get REAL. When it gets into boost its war time. Wanna talk crazy, punch the throttle and let it down shift, meth comes on, 044s kick on, and the speedo just cant keep up.
