Ok all y ou technical gurus.
What would stop you converting a MY01 to run a dirty great turbo with loads of lag but big top end power and at the same time running a supercharger to cover the low rev power?

I've been wondering this one since my MR2 turbo days so now maybe I'll get the question answered.

doesnt a supercharger run off the cams, so the more revs are going into it the more pressure its putting out, therefore no real difference to supercharger.

just my thought and understanding, may be completely wrong though.

Theoretically nothing...


They are driven by a belt... not nececarrily by cams..

Good Reasons..

Mapping of Engine..
Cost
Space
Common Sense

Just get a decent hybrid... or <FlameSuit>Anti Lag<FlameSuit>

Edited to add p20spd you mean a turbo and the idea is that as they are belt driven there is no lag (or minimal)

... or get a comprex pressure wave supercharger and get the best of both worlds.

The mapping on an MY01 would be reasonable for a supercharger, but the problem will be space, mounting the kit, and getting a suitable drive. As an alternative, how about NO2 set up to run only at low revs (1,000 - 3,000 rpm), full throttle and off boost?

sorry david by cams i meant cambelt.
i do understand that they work lower down the rev range than a turbo, i just thought the pressure built up as you went up the revs.

anyway been proven wrong, as i said i would be, by my superiors

i am sure i read sometime ago that they did a kit for the american 2.5rs, not sure though.

please accept my apologies for lack of knowledge obwan(dw)

Not sure of the technicals on superchargers but as far as driving goes they seem to lose all their power in the higher rev ranges (G60 corrado).

Seems like it would be a good way to get some goo dlow down power while retaining the power up high. Course I'm sure there are different superchargers just like turbos.

I'm just reading a 3 page article in Japanese Performance mag on Turbo Lore so in 30 minutes I'll be an expert on teh subject

There's a nice article on a modded STi V Type RA ..... by a chappy over there with you lot. He's spent £16,000 on mods and it's for sale

BugEyed... watch this space for no2.

Well basically the supercharger + turbo was the config of the Lancia Group B rally car.
This was the one that Henri Toivonen was killed in - basically way, way too fast a car . . .

Anyway, the year he was killed he took a journalist round Estoril GP circuit - they timed him & he'd have been on row 1 of the GP qualifying for that year, sounds great until you're doing it between trees & without armco!

only 16k on mods? that aint much

Turbo Technics fit one to Elises and the same system is used on David Brown's Exige. There's not much room in the engine compartment of those.

They run low boost from the ST (around 9psi IIRC), but this may be all that is required for the Rover engine.

The main advantage is full boost by about 1800rpm.

I'm looking forward to it. Is it a high rpm or a low rpm infill system?
