V6 Supercharged
- Thread starter wrx-172
- Start date
315bhp on throttle bodies alone without any cam or head work would not be that easy or possible i wouldnt assume.....but not tried it so done know.
The conversion would consist of cams, headwork, TBs, sectioned off cockpit, exhaust blah blah blah....and it would be designed to retain as much torque as possible.
I remember someone saying TB got 315hp on a car once not sure what other bits it had done to it though ie head work.
As for costs Im guessing about £4k any ideas though Ben? I would guess gains to be quite high as your doing quite a bit more than the racer have done to them and there at 285hp.
Id love to to hear the noise a Tb V6 makes though WOuld be a real head turner.
from personal experience, not that i have much some might say, simply putting throttle bodies on a car can be an absolute minefield of sh*t. hot air in engine bay airbox or not?, new power band, gear ratios, torque problems, induction length, i thort you could just bolt it all together and it woud be instant success, afraid not in some cases
not saying ben or anyone whos doing it isnt doing an excellent job and thinking it through
but just saying simply bolting on 4 throttle bodies and a remap is not the key to power like some people might think,
just like people used to think a k&n filter gave 20bhp............
THe people who decide to do throttle bodies then dont consider those most basic of considerations shouldnt be doing it.
The V6 conversion would have 6 SF type bodies with a custom manifold and sufficient length, which wold also be tested and altered (via diff length trumpets) on the dyno to see what works best for moving the pulse tuning effect upand down the power curve. The open end of the trumpets will also have a pulse plate behind to ensure that every last % of minimised turbulance is removed for proper isotronpic flow. Then a sausage filter will be placed over each bank of TBs, then an airbox placed over that with a sufficient cold air pickup.
Gear ratios arent anything to be worried about as were not looking to tailor it for a circut.
Japspeed did it but it broke - not their fault really bit of an experiment on an 11.4 comp ratio motor
Engine blew and was rebuilt by Damax and ex BAR engine builder with low comp pistons.
The V6 is very dodgy under forced induction due to heat build up and detonation issues - once pistons changed shes fine
I know this is my first post on an old thread, but have you looked into the way Venturi turbod the 60* V6 in the Atlantique. 10.5:1 compression, twin turbo, 7psi boost chargecooled on Motronic FI,
310bhp - 0-60 4.7 and 0-100 10.9
This was on the lower tune Laguna engine, not the Clio, but still fine of relatively high compression.
and very low boost - you can get 300 bhp normally aspirated with a bit of work TBs etc.
This whole engine is available from Huger in Le Mans.
The A610 was turbod by Renault themselves on lower compression to good effect.
The ignition r****d required at 10.5:1 to stop detting is why the powers so low. 100bhp per litre is a decent non turbo lump!!
400bhp is better when blown but you need a pressure ratio of about 2 to do it and a decent intercooler and ECU
The 610 compression is very low, 7.6:1, I own 3 610s and 2 GTAs. One of the GTAs is now running 8psi on 9.5:1 on 2849cc and is the most drivable of the group. There isnt a problem with detonation with aftermarket management on this vehicle, the others are running factory setups.
Which engine is available from Huger, 300 n/a or the Venturi unit.?
Renault Laguna Coupe
If you want an off the shelf supercharger conversion, supplied and fitted, you can get one http://www.novidem.chhere. Choice of 306 or 330 bhp, with 360 in development. Swiss company, so itll work, and you can have a nice holiday in the Alps while they do the work.
id prefer a NA engine setup myself.
benR - will the throttle body development keep the engine cover, as i and im sure alot of V6 owners would like to keep the original covering, i dont like the noise or heat in cabin, and a perspex cover wouldnt be of interest to me personally, although 300bhp would be!

They wont fit under the standard engine cover no
Renault Laguna Coupe
I leave in 4 weeks time

Ive been talking alot abot it, but im yet to come across anybody who will actually commit to a development program after initial talks.
