I've been made aware that a guy in OH is about to upgrade his Gen2 creampuff already running a Roe, to achieve a promised 925hp at the crank for an additional $12,000 investment on his part.
The car dealer in Mid Ohio handles sportscar sales, and installed the Roe that's on the car, but isn't necessarily known for having any of its' own tricks or 'magic' when it comes to creating Viper horsepower.
Thinking of SunRaKat ptII, I suggested selling the Roe and just going with a couple obvious tuner choices to install a Paxton.
As things go, he's lookin at me like I don't know what I'm talking about. Maybe I don't of course...
So, how about some feedback? Keep the Roe that's already on the car, and go $12k worth of upgrades aiming for the promised 925hp at the crank?
Or sell the Roe, and go with a Paxton intalled by a reputable tuner?

I love my Roe, but it can only flow enough for the low 700's in power per Sean Roe. The only reason I went to a Paxton is that Underground Racing told me that would be the most inexpensive way to get what Larry Macedo promised but failed to deliver.
I love the Paxton now, too. Underground Racing rebuilt and tuned my car in a fraction of the time that Macedo Motorsports took and still couldn't get the tune right. With Underground's tune my car drives very close to the Roe's characteristics on the street but has an unbelievable top end above 4,000 RPM.
My Roe s/c will be put up for sale soon.
Call Kevin at Underground Racing - 704-361-3443 - for info on the Paxton vs. the Roe. I certainly advise having Underground Racing install and tune the Paxton to your car.

There is a new Roe type blower that WILL flow more and it creates less heated air..... very few people know about it......VERY FEW!

How are they fitting a larger blower in there? I asked him awhile back (before i went TT) about the 3.3L Whipple that was being used in the LSX community. He said that there wasn't enough room. I can't imagine that that has changed.
You could probably make the manifold "thinner", but wouldn't that exacerbate the heat retention issues that are already present? Don't get me wrong, I am not criticizing the Roe Blower. It is good for what it is...a simple solid bolt-on 650rwhp (system only) power adder... a bit over 700rwhp with heads/cam/exhaust.

I don't even think I need any more information about the $12k in mods (unless it includes a huge shot of NOS), to call BS on that dealer.
925 at the crank is about 800 rwhp. The highest horsepower Roe cars out there right now are maybe 750 rwhp. That's 10 psi or more, water/meth, forged pistons, heads, cam, headers, exhaust, rockers, a killer tune, etc. I have not seen any Roe without NOS ever hit 800 rwhp. Ever.
Even if the dealer built him a new motor with forged pistons, rods, heads, cam, etc for $12k (which is unlikely) it is not probable that the car will hit 800 rwhp with the Roe without nitrous.

Mark, How much $ does it take to do the mods to get 750 RWHP with a Roe?

The obvious answer (though you're already aware) is MORE money than what your offering the TT's for. Which needless to say is a MUCH better option in this price range

Hell ya, call Underground Racing and KNOW that they will get you what yourwant. I just left Underground Racing today and couldn't be happier. I will make a post regarding that later, I'm beat.......

I was just curious how much people are paying to get that kind of power out of the Roe.
My 98 GTS with Roe @ 8#, water meth, modified air box, Hi flow cats and Random Tech exhaust had no problem putting down 598rwhp and 644rwtq with the rest of the driveline being stock.
My 01 has No Cats, Corsa exhaust, Macedo airbox, Macedo tuned Roe @ 10#, 708 cam, pushrods, 1.7 rockers, vac crankshaft pump and shouldn't have a problem putting down 720rwhp. With ported heads it should get close to 770 or more I'd think. I have a 100hp (read that that would generate 140rwrhp) on the car, just can't imagine turning it on (it's a virgin). The Roe makes hp at such low revs I would think that a 700rwhp Roe would compare to a 850rwhp TT or Paxton setup since they don't do anything until a couple thousand revs after the Roe is making full boost.
I understand the Michelin record is 10.4 (don't know how did it), but Davez went 10.5 in this car before I bought it ... with under 700rwhp at the time.
I drive thousands of miles in my car and have put on over 5,000 miles on it in the month since I bought it so super soft, only good for 4,000mi. tires won't work for me. Since I have new Michelins on the car and trouble finding traction below 80mph, I wonder what I'd do with another 100hp from the Nitrous?
If I drag raced only, then I'd run slicks and add more power, but I drive it on the street and won't put a roll cage in my car - so much for racing.
As far as street power goes, I have to plan where and when I step on the throttle. A few seconds at WOT and I'm well past any speed limit in the country.
I was eating a Z06 on my way home today and fishtailed after I passed him. He was impressed, I wasn't. Maybe after 100mph I could hit Nitrous, but I have no interest in even tryin that and don't drive that fast on the street.
If it's a street car, then I'd suggest the Roe as it makes hp where you drive the car and works at light throttle without high rpm. I don't think that because a TT or a Paxton mkaes bigger Dyno numbers it's the best choice, unless you only race the car.
My 98 GTS with "only" 600rwhp had Gen III rims and tires on it. It looked good, but it had NO TRACTION until you were going over 100mph. I thought I needed to get used to it, but it was the tires having minimal traction. My 01 has 18" VR1 wheels and Michelin PS. It looks nicer and has double the traction.
If you don't have a hate-on for Larry (who built my car) call both Underground and Macedo and talk to both of them.
Unless you're building a race car, then you need a GMC or a TT. You can cut a hole in the hood if it's only a race car.

Ted -
I beg to differ. put another way: prove it. Others have tried but none have succeeded. Your named tuner tried with TWO different customer cars to use Striker heads to make the big power... and twice he failed and blamed the heads. Those customers went elsewhere and removed the ROE and made MORE power w/o the ROE than with!
believe me, i'd love to see a ported-head ROE car that makes over 770. hell, i'd like to see one that makes over 750. In fact, breaking that 700 barrier on a ROE w/o NOS seems impossible to me so far. And I've built a couple to try!
When you add better flowing heads, the amount of boost (aka: backpressure) goes down. With a Paxton or a TT, you can compensate by turning that back up. With the ROE, you cannot. The blower is already spinning beyond capacity so all you get is heat with no more airflow.
Are you willing to spend 28k to become the fastest ROE car? someone else tried that and failed... So either back up your facts or quit keyboard racing; it is bad for the people who later use the SEARCH function because they may actually believe you!
