That's really not a problem. M3 has 11.5:1, and HPF has a production turbo kit that runs 12psi. On 91 get's 440RWHP daily driving.

On race fuel, 650RWHP. It has run 11.4 in the 1/4 a few customers cars.

Different technologies, but compression ratio is the same issue..and it really isn't an issue...tuning is the key.

They have built engines for the e46 available now but yeah all the kits like the Active Autowerks supercharger and most of the other kits just made sure tune is good and added alky/water injection for an added measure of protection. Things are starting to look good around here.

mike1324a

Yes sir. I think it will be a combo of alky, these bigger turbo kits, and ignition that will open the flood gates of power and products

Very rarely does anybody build a S54 E46 M3 engine. 99.99% run stock internals with FI up to 650+WHP on a turbo kit, that is on race gas. SC FI and alcohol injection gives you a bout 500RWHP, stock internals pump gas.

Otherwise, the limit is about 425-440RWHP on any FI setup on the E46 M3 running pump fuel that is reliable and won't detonate the engine.

Anyway...I am looking to move to an RX8 and sell my 03 M3. There are no turbo kits but one for $16k to provide 400RWHP. Only SCs are available due to the individual throttle bodies...you just can't do for example twin screws with that setup. Hence, your choices for the M3 are very expensive single turbo kit, or SC with a smooth linear power delivery. That is it for the moment. I am tired of 273RWHP with the M3..it just isn't enough power for me personally.

I personally believe turbos are more efficient and have generally higher HP output potential for not much more cost...and prefer that route. It appears in the M3 world some alternatives that are less expensive are on the horizon..but mine has 60K on the clock..and really want 400RWHP or close with a turbo setup..sometimes soon, don't want to wait it out another 2 years and miss out on turbo enjoyment.

Sorry for heading off topic guys...but hence why I am hanging around here..in fact, heading over to Mazsport in Largo this afternoon to maybe see what they got and get some rides in a boosted to get an idea if it is something I really want to do.

Good luck.

well im glad to hear you are going to be an 8 owner, make sure you post your results of your FI kit as i am interested

mike1324a

Yeah i keep any eye on other cars forums from time to time. Thats what i was trying to say, just not as detailed. It started out with "FI = kaboom" but now its becoming available and better, much like our beloved 8's story with hp mods.

sigtech

jajaja 500whp? you must be joking.

you can't get 500whp with any engine just because the tune is great.

RENE is just not meant for a high output.

even if all issues are resolved, RENE will NEVER make more than 500whp and run more than few hours.

chetrickerman

ha, we will see about that

sigtech

even 400whp will be tough.

people talk about ignition this tuning that, but just because one issue is resolved, that doesn't mean we'll magically jump another 100whp.

The douchebag with 10 posts that comes on the forum and tells us this is impossible when reputable people tell us it has already been done. Get a life.

chetrickerman

yea, and you obviously havent talked to chris

sigtech

cnnmn, you're f'ing idiot. eat ****.

sigtech

we've been at footstep of 400whp for AWHILE. fixing some ignition problem isn't going to rocket us to 500whp. that's all i'm saying.

Temper, buddy, temper... jumpy folk do get banned here now and then.
Sounds like a FIGHT is coming up
Lets keep it fun!

chetrickerman

when did we say that fixing the ignition would give us 500 hp

sigtech

will do RR. i suppose that msg is also meant for RG.

sigtech

i can't tell if you're being sarcastic or not, but rene can probably handle 50 shots or so with stock fuel pump, probably 75-100 with upgraded ems and upgraded fuel pump.

some form of FI can be reliable for rene. just not 500whp, or even 400whp, and i'll stand by that.

you can stand by it all you want, but we know its going to happen. AND the engine will last more than a couple hours
