I don’t have a recommendation. But I did love seeing your car at the burger king on Clmt Mesa years ago on Saturday nights. My cousin had the red supercharged 72 shortbed and the big block 64 nova. Dad ran the Camaros and the blown suburban. I had the blown 65 c10, now it’s “blown up”. That being said, prochargers are what my friends are running and running well.

 

For some reason there are some turbo guys that feel the need to convince everyone that turbo's are the only way to go. I don't think you'll get that from the Procharger guys. I think a person should go with what they are most comfortable with using and tuning. There are pro's and con's to both. I personally like being able to pull to the line and when the bulbs are lit, stab it and let go.

 

Staging is the biggest reason I went with Procharger.

 

Whats the average cost to rebuild a Procharger ? Including the lube .

I would tell you what it cost to rebuild a turbo , but in the 12 years , and 2 turbos Ive owned , Ive never had to do it .

Only reason Im on turbo number two is I outgrew the first one .

Im not even sure how many miles Ive put on them , but I average 10 to 12,000 miles a year .

 

He said f1x-12.
Not f1 or f2

 

To answer your question. I have built.....tuned........raced both. Everything being equal and properly matched, the turbo will make more net power. That being said, the turbo combination will be a little more difficult to get everything right,.....and a little more difficult to be consistent .

 

F1X-12.

 

I do understand the cost of turbo fabrication though , if you cant do some of it yourself . I wasnt thinking about having to pay a shop to do all that .

Prochargers are easy when it comes to building

 

Well that didn't take long.

 

 

My question would be: How are you delivering fuel?
I just started testing my turbo setup for drag racing. I switched to efi a year before. Honestly the efi was much more challenging than the turbo deal to me. Yes I am changing cams and converters, which you will do with blowers most likely as well. And yes the turbo deal is not bolt on by any means. There are the headers which will be custom, and probably not off the shelf available. Intercooler if you are running on the street and if you aren't running alky....but you may run an intercooler with the blower depending as well. Depending on the combo, the starting line routine may be more complicated with a turbo, and could leave you vulnerable to competitors who want to dick with you. Mine I am concentrating on being able to stage at idle and build boost starting with the first amber. But I am bracket racing and don't need to be all in at the starting line.
There is the cost thing. The turbo deal typically even after the fabrication is considerably cheaper than the procharger setup. When I was deciding, the reliability of the gearboxes was certainly a factor for me.(when I read the horror stories of gearbox failures with the prochargers and no help from the manufacturer....and the cost to fix it, that was about it for me) The efficiency of the turbo setup is greater. No blower to cost you power.
IMO, the turbo thing is really gaining popularity for a reason. EFI is almost a must with a turbo IMO. If you have good help through that changeover and initial tuning and learning, that isn't bad.
Now, if you want pretty straight forward, quicker to getting to good runs, and much of your power available at the hit without having to work at it, I think the pro charger deal is still an advantage.

 

I'm curious to as what the OP is using for a block and crank with a Buick combo,

 

Not sure what a Buick has in after market blocks and cranks but I would start there. Blowers are much harder on parts than a turbo. I prefer blowers. It takes to turbos to go fast ??

Somebody asked about my combination, I have an after market TA aluminum block, it can “take it”, and my crankshaft is a billet Moldex piece, all “good stuff”. I have 2 nitrous units on the car now, but there’s an issue with the 54 mm roller cam for Buick’s, they are not designed to be ground in a Lobe Separation Angle required for 500 + of nitrous.. So I’m actually in a shitty spot, and that’s why procharger or turbo would be better, and actually I’d be more competitive running x275...

If the cam is the reason for the switch you could have a tool steel core made, put the lobes where ever you want. Just an idea to help from changing the whole combo

 

I have run both and a Turbo setup is going to be more costly for sure especially if you are planning on running a 275 class. The Procharger will be better in an 1/8th mile race as in general you will get into your power band quicker with the Procharger than you will with the turbo. Not knocking turbos as I currently run one, but reality is reality. Much harder to get a turbo car competitive than a Procharger car as there are more parts to get to work in unison.

 

On a turbo deal when the pipe is full - you’re not getting anymore.
On a supercharger - it will rpm until it comes apart.

 

The Turbo and Centrifigal both run similar compressors. And both are designed to provide pressure within there Efficiency designs.

 

I appreciate all the information. I’m steering more towards the F1x-12, over the turbo.., Right now I have enough information to be dangerous, gotta scrape up more pennies, my cost figures were a little low after talking to The Supercharger Store in Az. I’m looking at $10k before I’m tearing into the high compression nitrous motor..... Gary G

 

F1X-12 is a bad ass blower. Friend went 4.20s with one with a AFR headed 23 degree sbc at 166mph. Car is not 275 legal ,but that blower makes some steam and has been durable.

 

How much power can a f1x-12 make on a small block?

 

Well, the damage is Done!!! I bought an F1x-12r, and plan on crank driving it. Supposedly made 2000hp on a 480ci sbf, so hopefully my 475ci will do the same. Probably start cutting and re-doing the core support next weekend, gotta make some room!! Good bye nitrous, Hello “boost”!
Thanks, Gary G

 

 

Boost gets you Laid !!!!!
