Largest turbo on single rotor?

m1tch · July 05, 2011, 06:47:38 PM

Hi everyone,

Whats the largest turbo a single rotor can support? Its a 660cc capacity, so its about a 1 litre capacity for a piston engine, would something like a T25 easily spool on it?

r magic twin setup used 2 td06. so i guess a td06 is a gd starting point

depends if your talking ultimate.

a 13b can support a gt47 if required.

since that flows around 120lbs of air, thats 60lbs per rotor

or a gt35 per rotor

ive seen a twin gt30 setup, but not a gt35.....probably because its cheaper and simplier to use one giant turbo

Tempting....

supercharger and smaller turbo set up as sequential ?

do away with the radiator, and use the rear rotor as a steam engine, the heat generated in the front rotor powers your steam driven rear - just need a steam condensing device (I believe there was an article where someone had this working on a renesis engine).

That would be quite impressive.

Final mad idea - do away with the intercooler - run E85 and get impressive intake cooling with the fuel injected early in the air stream - such as spray in on ITB\'s

Where is that lab I\'ve been asking for to try all these brain fart ideas out..... :Hammer :driving

GT40R, get it running on methanol = 500hp!!! would have to be a PP though, really want do this and stick it in a classic mini, rwd, be freaking awesome, no intercooler, hide the rad in the boot. wheres that damn lottery ticket. :rollin:D

gt40 on methanol would be more than 500bhp, id be aiming for 600bhp+ at 2bar with a massive amount of ignition.

ive been contemplating running mine on methanol permanently since it isnt a road car anymore.

it actually works out not as expensive as people think, since you us around 2.25 times the amount of meth as petrol to hit the same afr it might sound dear but when meth is 50p a litre its not.

50x2.25=Â£1.13 compared to 1.30 for normal petrol.

if your doing the hassle of E85 you may aswell go meth

ive already got a 2x044 pump setup and a fuel rail in my garage so its just a case of getting some ID2000s and wacking up the fuel pressure.

im alking a singlr rotor engine, one rotor and a GT40R.lo

dont forget lee that methanol is highly flammable, and dont know if race tracks allow you to run it

turbotoaster · July 05, 2011, 09:47:28 PM

well i hope your ready to rev it as id imagine it will fit a bar of boost on a bridgeport of around 7krpm, still should make maybe 250bhp!

Grant Monkhouse · July 05, 2011, 09:49:50 PM

and if you spill methanol and it ignites off someones fag thats looking at your car you cant see the flane

i have no plan to write on the side of my car in big words \'POWERED BY LOOPYJUICE\'

though if i run at time attack i wont be running it on meth as its against the rules, but i can inject with with a bit of water mixed in as thats legal

i have no friends who smoke and anyone coming to look around my car will get a punch in the spline!!

im talking about a PP, na it should be around 150hp, lol. add the turbo, 10,000 rpm methanol and boost and i rekon 500 hp wouldnt be too far off
