Trying to get all my ducks in a row and help with my m90 or R2300 decision.

Where's the best deal on the Roush R2300 kit? The best price I have found is through Roush ($5,800) which is hard for me to beleive as they are one of the highest on the m90 kits. I'm looking for the one with the tune as their are not any good tuners around my area.

Questions -
- Any idea why the kit without a tune would have a 12 month warantee and the one with a tune only has a 90 day warantee? $5,800 is a lot to spend for only a 90 day parts warantee especailly on a supercharger....
- Is the stock clutch OK with the stage 1 power or is that a must change item?
- My car is a daily driver for which I am not going to convert to a forged block. I know quoting desired RWHP is not ideal but I do plan to keep the car at 450 or below. I'm really just looking to be able to play around with the lightly modded 5.0's, SRT's and SS camaro's. Not looking for the fasted thing out there as speeds $$$ and I don't have that much $$$ so I know I can't compete in being the fastest. I'm looking for reliable performance that I don't have to worry about breaking something everytime I get into it (thus the HP limits I'm looking at).

I understand the R2300 is a far superior kit but knowing my limitations is it really worth the extra $1400-$1500 for the r2300 over the m-90?

$5,899 is a Bargain for that kit, if it's a complete kit. $4,800 is the price I found for the "tuner kit", which is great if you don't mind spending some more for a tune/tuner, injectors and KB boost a pump ( or if you already have those items)

It's a much larger 4 lobe Roots/Eaton blower, which will ultimately run cooler and effortlessly than the much smaller M90. It'll also have to be under driven or you will grenade your motor.

A lot of people running an effortless 450-525whp over on FNSweet.com and they swear by those blower. People often upgrade to the R2300 from the M90 over there.

You can run the M90, but keep in mind that to get the numbers that you do want, you'll end up spending money on additional mods (pulley/tune, CAI, CAMs, upgraded heat exchanger etc.) when you can just get the R2300 and be able to get those numbers quite easily WITHOUT additional mods, as long as you have the right gas (93), tune and under drive pulley.

The M90 is tried and true. It's durable and it'll last a lifetime. The R is the next wave of Roots design and everyone is on the Eaton 2300 band wagon.


My guess on the warranty is that it is a very potent blower, that most will not "putt around in" lol. Shiet happens, they're aware of that

I assume the Roush one, the R2300, is an identical twin screw design, not a male-female screw of the Whipple type.

If the R2300 is an identical twin screw design, I say go for that one. The identical twin screws have proven to be more efficient (they have significantly and consistently better compressor maps), and thus, they offer better max efficiency boosts per boost PSI than the non-identical twin screw designs.

I just read up on where a professional shop did a test on 4 different kinds of super chargers, and the Roush identical twin screw won out over all of them when put on the same type of engine and put on a dyno.

Well I can tell you beating lightly modded SRT's and Camaros will be easy with an m90. I have crushed them both. Crushed a ss camaro many times over without the blower. The r2300 is the beast, big time power blower of the two. Like Stealth said you will have to underdrive it so you dont gernade your motor. While the m90 bolts on and your good to go. It peaks at about 450 HP which is also in the safe area of upper stock motor limits. With your current mods you could just run the roush tune and have a safe fun car that can play with the other fast kids. But if you want room to grow to 500+ HP with forged internals then get the r2300.

If I were buying that kit, I'd get it from VMP probably, although assuming you need a tuner and a tune, its $5949.

Yates Performance sells the 2010 M90 kit for $4299, so I'd say it comes down to your budget. Thats $1650 less than the other kit... I'd get the M90 personally, and do the 500hp upgrade on it. It would land at like $4800. That 2300 is capable of more power than you'd ever need...

why play around with those cars when you can beat the snot out of them.
get the TVS, and play for keeps!

vmp says the m90 is good for 420-440whp with their 500hp kit with no mods other than the pulley and their tune. No need for forged internals. If you don't want to get into the motor at all it makes little sense in my mind to spend the extra. Trust me beating those cars with the stock 435hp m90 isn't hard, throw in the vmp kit and it will be no contest. Aslo i dont think roush does a tune for the r2300 do they? i thought it was all tuner on that kit as far as the tune goes.

Mudflap

The way I see it, most cars with 450rwhp can't put it to the ground anyway. I'd be surprised if the standard M90 wasn't "enough" for you OP, let alone the "500hp" upgrade from VMP in the event that it isn't. 400-420rwhp is no joke seriously.

ShaneM - Yes, they just started selling the stage 1 kit with a tune from Roush.

Mudflap - You have a good point. With the stock car and the 3:73's I already am spinning in frist and second gear.

I appreciate the info. It's sounding more like the M-90 is best for me. I don't have a big bank roll thus why it's taking me almost 2 years to get the funds to do the SC but more importantly I have zero intention of chaning out the shortblock and staying a reliable DD is priority 1.

actually, you get a much broader power range with the R2300 vs the M90, so it'll actually be making more power sooner even with the same max level of say, 420-440whp. The M90 is more peaky, than the more linear power delivery of the R2300 due to it's much larger rotors. Not only that, but it'll stay much cooler since it's not being spun as hard as the M90 is(maxing at). I gathered this info from owners of the roush site FNSweet.

If you're on a budget, the M90 is the best bet. That way you have upgradable options...
cams, LTs also make it a winning combination
