Reputable shop recommends blower...

[cmsnake]

I spoke with Bob Kurgan of Kurgan Motorsports. He just put a shop not far from me at all. To make a long story short, he recommends the Vortech or Paxton for my car. I asked him about the Roush/Whipple because I was kinda set on one of those, but he didnt recommend the roots type. He said the weak point for the coyote is the rods. Because the roots type makes a lot of low end, it also creats a lot of cylinder pressure and will cause more stress on other components. He also said the drive by wire throttle makes it very difficult to dial in for normal driving conditions. He said the centri will be much more reliable and since these motors love to rev and rev quick, it will be a better set-up overall. While the centri wont give the low end hit, it will be more reliable and more friendly for a daily driver. Its also cheaper. Quite a bit cheaper actually. He gave me a killer deal on install and dyno tune. Ballpark I should easily make 550whp on low boost and this kit will easily support 700 with fuel. I wasnt really even considering a Vortech until last week when I saw a powder coated black kit installed. It looked very cool. But I really wanted the roots type 'whine'. Ive kinda resigned to the fact that if I go with a centri it wont be an instant 10 sec bruiser with tires like the Roush because of the low end. It'll probably be more like a mid to low 11 sec car that will trap 125+, but if it means more reliabilty, it may be worth it.

Id like to get everyone's input and thoughts on this...

i was going to go with procharger but settled with a stage 2 roush from bbr having the low end power is what makes it fun on the street

 

[steedafever]

i will be going centri when i get a power adder

Are you on street tires? Im afraid all the low end will just blow em off under 50mph. Doesnt seem to fun to me. Maybe the centri will too, not sure...

i will be going centri when i get a power adder

For what reasons?

Roush is a TVS and the whipple is a twin screw blower, not roots. Both are as capable as the centri blowers. He recommends the paxton/vortech because hes a dealer for them. I would find another shop.

IMO you can't beat a PD blower on a street car. I've never been a fan of the extra plumbing of a centri.

Gotcha. I guess I shouldve referred to them as a 'positive dispacement' blower. Correct? Point being, that style creates a lot of cylinder pressure. But you may be right about the dealer issue. Ive heard nothing but positive things about Kurgan so far though.

No there is nothing wrong with Bob. He used to be out here in IL, but moved for warmer climates. He tuned my GT500 and made it happy. But there is nothing to be lost or gained with any of the current blowers on the market. You just need to decide what you want to do with the car, then you will be able to pick a blower. I think the centris would work great for the manual cars for drag racing. BUt the PD blowers for the auto cars for Drag. And for the street, the PD blowers are not to be beat in terms of tq. I had my GT500 pullied, and it would melt tires at any speed in 1st-3rd gears with the roots. It did fall off at the top end though, and that always pissed me off. It needed a TS blower to be perfect. And my pic for best blower would be the whipple. I personally want the procharger. I like the pkg, plus its cheap. I cant afford the $7k for the whipple. But if I had the cash, the twin screw whipple is the best all arounder in my eyes. Low inlet temps, lower than roots or TVS, but will still charge hard to the top like a centri.

I agree with u. Plus u don't have to worry what intake u should use. I used to hate the old vortechs because of having to run an oil line.

 

[Bad500Chris]

You should probably figure out what you want to do with the car first.
10 second street car?
reliable DD?
built race car?

Honestly if you want reliability AND a track car, just cut weight from the car and add bolt-ons. You'll be surprised at how quick these cars can be without a blower.

Thanks for the response. The centri's are much cheaper. Why is procharger your choice?

The new ones are self lubricated and you can use the factory airbox.

I want a reliably DD that will see the dragstrip and will trap decent for the interstate incounters. I agree these cars will get down with boltons, but by the time your done with those, the cost is almost the same (if you go the centri route). I think Id rather knock it out all in one punch and gradually bolt on from there when the current power level gets boring.

So true. Working for a few shops I was forced to push certain products because they were deeper on them. Not saying he is a bad guy, but he is going to push what makes number one the most money. Especially to someone who calls or comes in and does not know exactly what they want. TVS or Whipple will be more fun on the street. The shop I was at pushed Vortec and Paxton(same company btw). To me they just are not fun on the street compared to a roots or twin screw.

But what about street tires? Im assuming the PD will just boil them around town. Correct? Like I said above maybe the centri does the same, but it seems as though the power gradually comes on to wheelspin may not be as big a factor. Its my DD for now and Im not in the mood to run a drag radial all the time. And when the cylinder pressure issue was brought up, that didnt sit too well.

It is all in how you drive. A centrifugal blown car will destroy the tires the same way. A stock 5.0 destroys the tires. You could start elsewhere for mods. Cold air, tune, h or x pipe, suspension mods, wheels, and tires. If you go with a blower go Tvs or whipple with a plus zero on the tires. Something with a 300 treadwear. 275's won't spill off the wheel and will be much better than the stock Pirelli's.

 

[alex12gt]

youll toast tires any way you go.....thats the fun of it and before i went with the tvs i had decided procharger because of the fact it has its own drive belt and i am doing my own install and the procharger kit look to be a more simple install

Cost was number 1, but being self contained oiling also played a factor for a centri. Not to mention that these cars pull to 7k+ and the centri is going to make power as fast as you can rev it. I dont see my car as a tq monster as the GT500 was. I would rather have that top end now, and spare the low end tire smoke. Plus the install of their kit is very simple and it looks very professional under the hood. I like the standalone drive system for the blower.

I've had twinscrew cars, turbo cars and now a centri car. And this car with a procharger is by far the biggest beast. It's a blast to drive. And with blow the tires off in 1st second third and break them free in 4th.

They all work well and with the right set of gears you can more than make up for loss of tq down low.

It's all about what you want and what you'll use the car for.

 

[MikeLTDLX]

Shaun went 11 flat at like 125 with just a couple of minor bolt-ons and one of his tunes. Personally, I would rather have a well tuned bolt on car that runs low 11's, than a supercharged car that runs low 11's. Supercharger or Turbo = 10 second car in my book.

Of course, it is easier (and more costly) to do with forced induction.

Lol you've never raced at elevation. NA just doesn't work for some people.

 

[LS2GTO]

He also said the drive by wire throttle makes it very difficult to dial in for normal driving conditions.

Rule #1: If a shop is pushing you away from a certain build because they don't feel like tuning it because it's too complicated then it's time for a new shop.
