Supercar Engine Poll

theoreticaly we coulduse a modified 1st/2nd gen eclipse driveline as an allwheel drive setup, the 6 bolt 4g63 could take any amount of power you wanted to make within reason and with a reverse gear transmission we could have awd with a rear wheel power bias... just a thought, or how about a dodge srt-4 motor mounted mid ship? it is bullet proof stock and makes amzing amounts of power and torque for its size.

don't know on transaxle but engines can be sourced at Ford still...price not sure,second hand around £1500 complete,Mountune in UK will supposively build it to 550Hp with all extras for £10000 after you give them basic engine.They proved very reliable,only downfall was Turbo in race conditions running too hot for too long ,but they still won Bathurst in some prettiy torturing conditions

Amerspeed 383ci supercharged V8
640bhp

I went with the turbo 4L Ford engine, btw is a straight 6 not a vee. it has AMAZING potential power outputs... FPV_GTHO will tell you all about it im sure

[megotmea7]

an DOHC straight 6 will be a pretty long and tall engine compared to some of the other choices we hve here, and d say it weighs more than a LS1 also with less potential. and as was said were looking for around 500hp, we dont exactly need an engine with amazing potential as we wont take advantage of it anyway making 'only' 500hp. im still for the LS1

I meant the Mondeo 3.0 Duratec, as used in the Noble M400

[Matra et Alpine]

hmm, yeah didn't think about the Duratec. You got weight and sizes for it.
It's got lots of options for mounting once we chose the UCP layout

SHoudl it be added to this poll - seems like it went off half-cocked with lots of US engines ( maybe not bad given the 160ks rebuild )

AUDI RS6 TWIN TURBO V8 love that engine...

[megotmea7]

people we have to consider all aspects ere,
FIRST concern is getting it under budget, hell a 360 modena engine would be perfect for our ap but id toesnt mean we can afford it,
SECOND concern(at least for me) is to be reliable enough to put in a street car, which is what this is going to be remember.
THRID concern is to be able to make the amount of power we want relaibly while still being as light as possible.

think about these before naming motors. IMO the powertec is to unrelaible and might be too expensive, no clue as its not even out and no price is posted on it. any audi/bmw/etc motor would be prohibative from their cost and still having enough money to modify it to reach our power goals.

Remember Egg-Nogs confirmed guildeine that the engine has to have a 160,000kms between rebuilds.
As stated when that was announced, out goes the Powertec
Also pretty much everything else except for an untuned LS1 !!!!!
Any other engines anyone is going to put forwrd you HAVE to put up the engine weight and dimensions - and if it's a turbo you have to include the turbos in the size !!

FORD XR6T STOCK ENGINE:

Engine Specifications
Cylinders: T6
Valve Gear: V-Dohc
Turbo: Yes
Engine cc: 3984
Bore/Stroke: 92.26x99.31
Compression Ratio: 8.7
Power kW: 240
Torque Nm: 450

FORD F6 TYPHOON:

Power 367 bhp / 274 KW @ 5250 rpm
Torque 550 Nm / 406 ft lbs @ 2000 rpm
BHP/Liter 92 bhp / liter


all of this is easily modifiable to well over 500bhp with kits from APS and a few other places...

[megotmea7]

wieght? and it will have a higher center of gavity and be physicaly larger than an LS1 while producing less torque

[PerfAdv]

Depends what kind of curb weight the car will have. If the car weighs about 1,000 kg or 2,200 lbs, a smaller displacement high revving engine would be better suited, for a gradual more controllable buildup of power. The Radical V8 is nice but might not have enough low end to pull 2K+ lbs. Also from this list 4.0 litre M3 engine sounds good.

Naturally aspirated should definately be preferred over forced induction. Less weight, less complexity, less heat, more reliability, and better more controllable power delivery.

I think a Nissan V8 might also be a good option. The 3.5 liter V8s used in Indy racing are very light weight and very powerful and even the reg 4.5 V8 in production trim make a healthy 340 hp. A detuned Indy 3.5 or more likely a highly tuned 4.5 might make for an excellent supercar engine.

[Blue Supra]

OK so then if you seriously want to go with the LS1 i HIGHLY recomend one of these to go with

[Matra et Alpine]

yeah, but for SURE you're not 160,000ks between rebuilds

ALSO read the warning about heat We'd have to contedn with that.

AND heavier clutch, 'box, diff, brakes and with the extra weight heavier suspension and steering and THEN bigger tryres with more unsprung weight.
