Hi guys, I have a 19 Z that should be arriving any day now. Instead of spending money on the factory blower I having been thinking about just swapping to a Procharger. I was just wondering how much faster you have gone with just the Procharger without getting into the cam etc.

Good question . I have the pro charger installed but theres no tracks where i live . I can tell you that the low end torque compared to stock does not exist until 4000 rpm with the pro charger , you really need to use the gears . Hopefully someone else can chime in .

Just a procharger with no meth or anything will put you around 700whp. Depending on tires it should net you in the low 10 seconds @ 136-138mph range.

Kazman1960

Right on with the power estimate , with meth and headers im at 760 rwhp . The powers up high in the rpm band .

Doing an F1A build now and my original thoughts were staying close to bolt on with just meth, but chose to go with supplemental port injection hearing more advice and feedback from good people here (ProSpeed ACM + G1Pro intake + WeaponX 550lph low side) to hopefully get me closer to 800 wheel. Problem is finding a tuner close to where I live that will pull it all together. Hoping I didn't regret making this build so complex. I have a brand new Alky Kit that I am just holding on to in case I have to fall back to it. I wanted this is going to be a great experience and enjoyable especially doing most of the work myself, not something I regret.

What 1/4 mile times are you looking for? M7 or A8? Tires?

You'll probably find bolt on PC Z's going same times or slower in the quarter than bolt on stock cars.

A Procharger will make mad power up top and a lot less down low. On the street it will be less fun to drive.

In the quarter mile, properly tuned, it -could- be faster. But make sure you understand thet tradeoffs in going from a positive displacement blower to a centrifugal. It's not all winning.

Pretty much summed it up .Yesterday I was actually thinking of going back to stock , stock blower with just general driving around in my opinion cant be beat , however , after a longish drive out on the highway with a bunch of other vehicles , the pro charger is a different beast above 3500 rpm , you really do need to use the gears to extract the most out of it .

Had a guy at sac was running 9.60s. Pulley/meth/cam/heads/long tubes/intake.

ended up going procharger and went 9.51. Gained 4 mph top end but lost a lot of low/mid. He said car pulls great at higher revs but for drag racing he said he should of just spent it on a bigger blower.

car also made 170 more at wheels peak.... but along the power curve was a lot less.

BooSSted

Yep, you need to be cranking some serious HP to dive deep in the time slips. My car made 864 on pump, and was running 10.4s summer. **** 60 foot, so so DA. But MPH wasnt great either. Cars going to a new tuner going forward, pretty sure its dropping boost during runs.

If i did it all over i would go with the PD blower heartbeat or 2650 non edlebrock.

Kazman1960

The one thing ive noticed on my own car is , with the Pro charger , I find it easier to launch than the stock set up . Now this maybe to do with the lower amount of torque available off idle with the pro charger as the torque hits way higher in the rpm band . Also , my car is stick not auto . Easy to blow the tires off at launch with all that torque . I realise im not as good a driver as people who frequent race tracks but that's the way it is here where I live. Next month however , theres a local group who have rented an airstrip for a weekend of 1/4 mile racing . I think im gonna try it and report back then .

agreed, PC is sick on regular car, loss on z06. there is def better options out there

Personally don't quite understand spending $10k on a procharger and not going with complimentary additions such as fuel, long tubes, etc. If you have a budget less than $12-15k no question heads/cam/cooling with a PD blower upgraded or pulley swaps is best path. For best times and high HP PC is crushing it just a few searches finds many like this:

BooSSted

i know the question is for just bolting up a PC but i don't think anyone is actually doing that. As usual the PC ARE on top of the fast lists. But for every shop car or crazy build; theres 10 PC cars making 900+whp with pedestrian times considering the power and what the car is capable with the stock blower. Talking purely quarter mile.

0NORCAL-SS

that is 40k build

C5-VERT

Easily. I am up to near $25k on my build already minus my signature wheels/cup2's. That's without cam/heads. That's my point. You won't make the most of a ProCharger build without fuel, exhaust, valvetrain. Even clutch, tanny mods. For $12-15k in my opinion you are better off with 2.3 or just heads/cam/long tubes/tune. The stock blower with additional cooling / pulley and heads/cam will easily make best use of stock fuel system as we all know and be a better road car. We all know going past that magical 800+ number requires a LOT more in terms of fuel, valvetrain, etc. Same problem I just ran into.

Guess I took this thread off topic my fault. Just may help those who run into the same issues I did...

0NORCAL-SS

no prob we all like info. Worst thing is when a car makes 150 to 200 more then a bolt on combo car and runs about the same times at the track.

wish ya the best on your build

Yeah doing a procharger as just a bolt on mod is worthless and you will more than likely be slower at the drag strip then just doing simple bolt ons to the factory setup. It's all about that 60' in the quarter mile and the procharger is going to be a comparative turd out of the hole. Unless you are doing a fuel system, cam, converter, etc the procharger is never going to be able to make enough bottom end to get that 60' down to where it needs to be to really shine.

That's exactly what I realized when I got deep into it. Now it's more about just enjoying doing most of the build myself, learning as I go (nothing like problem solving), and meeting good people such as yourself, Earl H, Drew, Tim @ ProSpeed, Ben @ Weaponx, Jason @ Katech, David @ Vengeance, Cesar @ TPS. Everyone has been patient and very helpful with me learning and making mistakes. That's what it's all about in the end just enjoying what we have and how we got there.

Just like those catless downpipes you make for the money and for most builds those will give you 80% of what you need for a third less than long tubes. Finding that nice line between cost per horsepower is all about research and also real world testing. It's also great to have so many options today. Thanks for the kind words!
