Rumoured 300BHP RX8

[Spectre26]

Spoke to the dealer again today. Once again he assures me it will be ready for sale to the general public before christmas. But the release date is pened in for next month.

A small update. He says they r releaseing a 260 Bhp model as well as a 300Bhp model. Asked him again to confirm if it was F/I he confirms again that it is purely N/A. I did ask him if he could call me when it is next in house and i will take a load of pics for the forum and hopefully manage to get some form of dyno paperwork to sway the unconvinced multitude:p as well as to satisfy myself about this too good to be true scenario.

He did comment that the car outwardly looks very stock but under the hood it is a different story. Main difference he mentioned was a large air box. Didnt really ask for any more of a discription, after all, at the moment, why bother? At this stage i believe every1 is in the same school of thinking as i am... the talk is cheap way of thinking. So for me its just a case of waiting for his call and popping down to snap up some shots and get some hard evidence to post up here:)

BTW just keepin u guys updated so dont  :flamed the messenger, but by all means discuss away

This has come to MRC via TW Whites, and from about as high as it comes, more will be released as they are nearer launch, so be excited..................

"Can’t answer all your questions at this present time but here are a couple of facts that may be of interest to you.

Current RX-8 has 231 at the flywheel and 154 at the rear wheels,we have a Dyno print out on our vehicle of 300 at the flywheel and 210 at the rear wheels.Torque has been improved but not as much as we would like. Not a turbo (you can get those from Japan) or supercharged.

We should be in a position to come to the market in approx 2 months and hope to launch it at the MPH Show where we will have it on the T.W.White stand.

Retail price will be under £30k which will include a full Mazda Speed Body Kit.The car has been lowered by 30mm and the brakes have been uprated. The handling is better than the current RX-8 but I still need to sort out the warranty on this vehicle"

The current renesis 2 rotor n/a engine in the RX8 is never going to get close to 300 bhp, trust me! It\'s pretty much had all the power extracted from it in its stock (hi power) form.

Hmmmm. Sort of getting interesting...................

[ScuttleRX]

definately, 300bhp without FI, just imagine it with

that equates to a 33% power loss through transmission.

Think there figures are very optimistic or mazda have made a real arse of the transmission.

I was thinking that - same goes for their claimed 300bhp at the fly: 210 at the wheels does not usually get anywhere near 300bhp at the fly.

hmmm....

Assuming the 8\'s transmissin is no worse than the Fd\'s (it\'s newer technology so I would hope it\'s improved) then 300 fly would give in the region of 245rwhp not 210!

If the car\'s not readys then TW might be hedging their bets and it may produce something close to 300 fly but if it\'s putting out 210 at the wheels then I\'d put money on it not being a true 300 fly.

What he said! ^

[g11ary]

Does seema lot to ask of a n/a system, but looks like we only have a couple of months to see the results, I wonder how bad the mpg might be, to get 300 bhp n/a

[iaint]

Will try to get along to MPH again this year so it\'ll be interesting to see what they are claiming on their stand!

[webrx8]

The RX8 231 dynos around 175 at the wheels give or take 7-8 bhp. Which is around a 25% loss. I suspect 154 may be a typo. I don\'t know of a single car that has dyno\'d that low.

Agreed, we\'ve had a number of HP\'s on our dyno and they have all made +/- 175atw. Stock any way :evillaugh

What\'s the maximum anyones got out of a N/A 8? with what  mods?

Thanks

[maximtaylor]

The stock car has had pretty much its full potential extracted from it already.

I\'d love to see a more powerful one, but I think that much more would be a struggle!
