479whp ~ 427 ft/lbs on OEM Longblock!

Was he on stock ECU and tuning with an SAFC? C16?

Yeah slight difference in mods I would say lol. I don't know if Alex wants to go that crazy without a built shortblock, but hey we can give it a shot!

It should be good. My wifes 1G puts down 384awhp on the DD with a factory mitsu longblock with the metal Mistu headgasket, HKS 272s, 50-trim@26psi, 1G MAS. The turbo is just about shot on it, so I want to goto an SC61 and wasn't too worried about the motor taking it. Nash's motor went through hell and held up for a while.

You two got married?

Once again I'm not worried about the 1g rods. I am worried about the pistons. 2g pistons are known to hold up to substantially more abuse than the thin land 6bolt pistons. I have seen countless burnt/cracked ringlands on OE 6bolt motors. I must say that Nash's motor did take a SHIT TON of abuse though. I've never thought a motor was going to blow up so much in my entire life than when I heard he was running 40lbs.

We'll see what happens and what Alex wants to do. I think if we hit 510-520whp and take it to the track, we might like the results! There will be no C16! E98 will probably max out his injectors, so we are stuck with E85. Hopefully the Walbro 255HP can keep up.

Yea, we got married last fall.

Why no C16? Just because of cost?

Yea, it's always a risk pushing a car that far. You never know if you got the factory freak motor also or the one they built right after drinking a 6-pack at lunch. :)

[dumb_ricer]

Because C16 is too easy!

The way I look at it is it is a low compression motor running a fuel that "cools" compared to gasoline, and makes more power than 110 octane, there is no need for C16. That and it cost's a boatload.

I don't see why we can't make a trackable 525whp. And then tune it back to like 450 for daily driving.

Mike still didn't blow up his motor at 585 whp, he just pulled it to be on the safe side. He's very careful about everything he does to his car including tuning, so you can be sure it lasted that way due to probably never seeing detonation. I'm sure 600 whp+ on a stock block is feasible with careful tuning.

You're thinking of the big three automakers. I don't think they allow unions in the Japanese owned American plants. :biggrin:

What kind of airflow #'s are you seeing? Surpised the 2G MAS isn't freaking out yet.

I ran a stock block setup as well for years making 500+whp never had any problems.

[dumb_ricer]

No idea on air flow numbers.

I am equally suprised the 2g MAS isn't getting outflowed yet.
