high CR high boost
Turbo Mini Forums

Hydrazine is carcinogenic.

I used to deal with it regularly (it is used in power station boilers to remove oxygen from the water), and had to put on a full chemical suit just to pump over a small volume of it through a sealed system.

Nasty shit, stay away from it.

this is interesting stuff.

I am just of the phone with one of the larger turbo/turbo engine experts in Norway.

We talked a while about putting a turbo on my K16V 1343 cc engine.

I told him that I would need to run a 32 mm restrictor (due to class regulations) he knew about that as he is already competing in the extreme class in the same series, with a audi S1.

He asked quite a few questions about current engine spec, things like cams, CR, pistons, volume, max rpm and the like.

I then asked him what he wanted the CR to be, if I should be running with a turbo. He wanted it to stay where it is, at 12:1. It would be fine if we ran it on E85 and played a little with cam timing. I think this sounds quite extreme, is it at all possible? He would then aim for around the 230 hp mark with max rpm around 7500.

they run 12:1 comp on some turbo'd hondas without problems of det

Sounds interesting.

If something is worth doing, it's worth doing half of.

12:1 is a walk on the park on E85 :) jim, the turbo hondas (as i found when i dug deeper) run race fuel (110+ octane) or E85

old post anyways, my car has ran 9.5:1 and 30psi to date lol required water/meth injection on normal pump fuel though.

turbo 16v k-series 11.9@118.9 :)

Denis O'Brien.

It's still interesting.
Honda running 12:1, aren't they vtec ? Perhaps with modified cams to retard ICT to lower actual CR.

std 998 A+, g295, MD266, RHF4, 109hp @0.8bar/5400rpm

Considering i do about 200 miles a year in mine I wish id looked into e85 now!!!
