New 2ZZ-GE S/C....anyone want to import?

[aerospike2002]

At the Geneva auto show, Lotus MotorSports just revealed an Exige with a supercharged 2ZZ-GE. The S/C is a piece of art. I could seriously purchase this engine with it installed just to keep in my room and look at :D

No specs have been released. Also, it may be interesting to try and fit the top-mount I/C into the engine bay.

Hopefully, Lotus MotorSports will make it available for the U.S. Looks like the decision to put the 2ZZ in the Elise has come through for us again in new aftermarket support!

wow, thats beautiful.... the aftercooler could be relocated if need be.

[dmaxd03]

WOw a front mount would be nice. I wonder if the s/c would fit in the celica. Wonder price and will it be the 249 hp like the exige?

[redscare]

It would take one ugly hood to house that
I/C. I'm sure someone will come up with a way to relocate.

now THERE'S a view i WISH i had :wtc:

[Smaay]

that can be easily modified with a front mount....its very nice looking...

[Black_TRD]

very nice wonder how much power it is putting down

[King Torq]

why modern designers would ever use an eaton is beyond me, it reaks of a 'cost b4 quality' decision-

fyi, love whipple/KenneBell type, love centrifical sc, love turbos, but the eaton,... it just blows in a bad way

BWAAAHHAHAHHAA....

I agree though...it's like I can't figure out why Jackson Racing still holds to the theory that the Eaton or Roots type S/C's are "the way to go," because that is all that they sell... :confused:

Centrifugal S/C's are obviously the only way to get things done nowaday....

[spaztikid]

eaton blowers produce a flatter torque curve with linear power across the rpm range, making it the ideal choice for adding throttle response and streetable low-end power.... something that the lotus could definately use...

[EastcoastSpeed]

Looks good , whos up for the first install :chuckles: ill do it for you.

I kinda thought that the eaton roots , was closer to the Lysolm scew type (whipple), than the older style roots blowers? dont the lobes kinda have the twisty design?..I thought that their efficiency was better than 50% like the old roots blowers were.

[Korben007]

oh i like this tread as i decided to definatly supercharge my tread. keep up the good talkin!!

[Korben007]

actually it looks like the supercharger itself will have clearance issues with the radiator and what not. The blitz blower is angled to just fit in the engine bay and the alternator looks like it would have trouble too

Well, take note that this is made for the engine bay dimensions of an Exige, not a Celica :chuckles:

As for the Eaton thing - I was under the impression that all of the Roots type blowers are outdated now, since centrifugal has been introduced :confused:

[NCspecV81]

how are you gonna close the hood?

[dmaxd03]

by lowering it and letting the latch click into place.
Really moving the after cooler should be pretty easy with a bit of piping. The question is whether it will clear the rad. It seems like there is a good bit of space in front of mine though.

Does the lotus head flow much better than the celi?

[King Torq]

i love all the ford aftermarket testing that is comming out of simple swaps of pulling the eaton, and straight bolting in a whipple (modern lightnings and cobras)- around 30% cooler, 20% more power at same boost, and way better long term life span (eatons degrade at friction points pretty badly, and vibrate engines to death when spun hard).

but i guess the fact that eatons are dirt cheap to make, or for aftermarket to buy used and rebuild and sell as new,... has nothing to do with its popularity.

you can get that monkey nose looking hood that sombody was tring to sell. but seriouly it could be made to work with a little fabrication.

I guess the eaton design is not so good....I just though that their efficiency was better ... Maybe it is only about 50%,... The Lysolm screw type ( whipple/autorotor) are suppose to be like 90% efficient....those are turbo #'s!!

Oh yeah.....nothing!!......heh, heh.

[J5ISALIVE]

would this work on the MR2? seems like it be perfect for a 2zz Mr2.....

I'm seriously debating picking up a 2000 Mr2 this summer and doing the 2zz swap......this could be interesting.

[Korben007]

well then i think someone needs to make a whipple blower kit for the celica

[Ricky,P.R.]

Here you can find the specs. www.grouplotus.com

[cool2miketlu]

Ehhhh they do a limited production of this on Lotus and it carries a huge bill, they will not just sell the upgrade is what I heard. It is only available to their complete race vehicle.
There is already SC choices out there, get Blitz if you want one for 2ZZ and get TRD if you want one for 1ZZ. Besides even if they offer this "kit" it would cost too much just because of that Lotus tag on the kit.

Don't forget about screw-type superchargers. They maintain much better efficiency at higher rpms/boost while still giving the low rpm response of a roots-style charger.

But I agree, I would much rather have a centrifugal s/c over a roots blower.

From Group Lotus:

"Lotus Sport, the performance division of Lotus Cars Ltd., has developed the Lotus Sport Exige 240R, a limited edition high performance sportscar with total global build volumes kept strictly to 50 cars.

With a supercharged and intercooled high revving engine producing over 240 hp and over 170 lbft of torque, the Lotus Sport Exige 240R reaches 60 mph in less than 4 seconds and 100 mph (160 km/h) in less than 10 seconds before topping out at 155 mph (249 km/h). At this top speed the advanced aerodynamics produce 113 kg of downforce increasing grip, stability and safety.

The 50 versions of the Lotus Sport Exige 240R will be built as post registration official factory conversions of new Lotus Exiges. Up to 40 of these cars will be sold in the EU and the balance is intended to be predominantly sold in Japan. The suffix of 240R indicates the approximate horsepower of the engine, conservatively rounded down from the actual figure of 243 hp (181 kW, 247 PS). The total unladen weight is approximately 930 kg and the power to weight is approximately 261 hp / tonne (195 kW / tonne, 266 PS / tonne).

All 50 cars will be built to order and to further identify and maintain the exclusivity of the Lotus Sport Exige 240R, they will only be available in Sport Yellow or Sport Black

"twin oil coolers and an Accusump."
Be interested in this...

The standard Elise has these same twin oil coolers. Not sure about an Accusump. Lotus felt that the oil problems exibited by the 2ZZ were related to cooling, not to inappropriate pressure or circulation.

so the blitz is a roots type? why did they choose the most ineffecient kind

[genax]

the exige isn't a ff car is it? is it just me or does engine look to be designed for a ff car?

The Elise and Exige are both MR.

And the 2ZZGE WAS originaly designed for an FF platform (and MR is basically the same thing, the engine is just moved behind the driver, and it keeps the same orientation as it would if it were mounted in the front).

[boostjunkie26]

Cost.

[Bimbleuk]

This is quite general but...

Classic roots (straight lobes) 45% efficient
Eaton twisted lobe 65% efficient
Twin screw (internal compression) 70-80%
Centrifugal/turbo 60-80%

The Eaton is good for applications below 12 PSI boost because even at idle the twin screw is compressing air which lowers efficiency.

The twin screw has an adiabatic (air pumping) efficiency of 92% not quite the same as the overall heat efficiency of 70-80%

[Korben007]

Isnt the blower in the blitz kit an eaton based blower?
I though eaton and roots where the same.

[Bimbleuk]

Eaton have the patent for the roots blower with twisted lobes. So yep the Eaton M45, M62, M90 & M112 are all modern roots blowers.

The Blitz blower is a fairly large capacity classic roots design. Not very efficient and very noisy (noise is wasted energy don't forget!)

This is true....the thing sounds like a jet engine on the dyno...

[Korben007]

sound are cool sometimes though! but in the case i would give it up for the power. I think im gonna go with a custom kit.
