so what are u guys making for power on a forged 346ci..preferbly on pump gas. i got a good deal coming up this summer on one i'll be using my 6.0 heads to start and for the cam..not sure yet. but hoping for around 650-700whp if the T70 can make it

There are plenty of guys running forged 346ci with F/I and making around 650-750rwhp. It's all about the combo.

I agree, plenty of guys making lots of power on the stock 346...
That's the way i'm going - keeping my 5.3 heads (since there a good amount of port&polish work) and going with a -16cc dish Mahle (3.908 bore) forged piston to bring the CR down to 9.0:1 (w/ .060 head gasket)... stock crank, eagle forged rods, and Twin T44's... project will be done by the time the snow melts...
I'm expecting 650-700 whp... street only monster

my set up is like the tti street kit now and prob kep i with the forged motor..need the money for a rear end and some more tranny work. thinking of the ingenfelter cam orsomeother kind of custom grind. this motor made 650+ in a vett with with a procharger

You will not make it to 700 regardless of your combo if your on pump gas I am trying to get the most out of my combo on pump and am shooting for 650 and it won't be very easy. FYI. 650 is the limit with pump and no meth, just intercooler.

more then a hand full of people have made 800-900 rwhp on 93 octane with no meth.

even on a 346

Who and was it with twins maybe? I would like to know the combo. I have never heard of it. What kind of compression are they using? Super low or what? Anyway there is no way he will make it to 700 with a single T70. If he does he's very lucky and needs an M6 for sure.

you talking to me?

iTrader: (2)

You or Tiago I don't care.

SSilverSSurfer

iTrader: (8)

yes its twins(t70's), no meth on 93 just like he said


i agree with you on the 700 with a T70 tho

Well then right on it can be done with lots and lots of turbo and very low compresson I am sure. Would be best for racing the 1/4 not the street. I am shootin for 650 rwhp with my setup and an M6 on 91 octane no meth just my good old intercooler rated to 1100hp. I think I can make it even with a safe tune.

I think 650-700rwhp thru an M6 is achievable with 346ci and pump gas, no meth, but that's where most folks would be battling high IAT's and also having to put their timing really low.

yea thats what i figured..my turbos rated for 900bhp i think. the motor came from a pro charged vett that slowhawk did. no one of friends has it right now

I will land somewhere in that window hopefully the intercooler upgrade Marko gave out will help make the power on 91octane. I will be posting in the next few weeks my dyno sheet and the amount of boost we were able to push along with timing and all that. We will see what this STREET KILLER can do with 91 and a TC76MPS.

i'd like to get some race ga numbers too for the track/street

52172

iTrader: (2)

I was thinking about race gas also, but I don't think I would ever use it enough to justify paying all the extra for further tuning.

SSilverSSurfer

iTrader: (8)

no 93 in cali? should find some race gas

Tiago

iTrader: (27)

if 8.6 CR is super low I dunno I think thats medium as far as FI goes.


And they are street cars, no race cars.

I think its possible to achieve those goals on 91. I'm shooting for around 680whp this week on stock cubes with a TC T76 and 14 lbs of boost.
