Noob to M30's

[T_C_D]

Hope you didn't kill the engine running it so lean. Surely it was detonating. Nice tq number. This is a stock m30 with a big cam, right?

I would have shut it down before the AFR got anywhere near 14:1. 15:1 at 17 psi is insane.

Ya, that is pretty intense. The significant "noise"(high cylinder pressure fluctuations) in the torque trace really looks like there was detonation in the 5k and up region.

Stock B34 ARP's MLS w/schrick 284/280.
Detonating for sure from 4600 and up. Engine still running...for now 2nd pump must have shit the bed on the way there.
It should get closer to 500whp with more fuel, I deff think it can handle 20psi

[e30-m30_kid89]

Damn, you make such damn good numbers with your m30. E85 i guess is really ftw!

Fix the pump and lets see 500whp plz thx!

[Scottinva]

22psi on pump, you can do it.

[BadM535i]

You can make 500 hp, but not for long. I know guys that made 600 hp on stock bottom internals but their pistons didn't last long.

[babisbabou]

Nice numbers there!!!!

Keep up the good work!!!

Aren't ring/land issues typically a symptom of detonation? G&T is running E85 (burns cooler anyway) so maybe he has more room for error...

[90e34535i]

22psi shouldn't be a problem with good tuning. After a few months of running 30psi on my stock m30b35 + ARP's + fresh stock head gasket(+ alcohol injection), every sealing ring on the head gasket expanded sideways and oval-ed out(mostly cylinder 3,4,and 5). Pistons are still in 1 piece in the block, but I'm sure theres some cracked ring lands.(over there life they have seen a lot of detonation while tuning/upgrading).

I ran low-mid 20 #'s for a while with no issues though.

Get some more fuel and I bet that hp number will be much closer to your torque.

I guess there is only one way to find out It's been at 17psi for awhile now so it's been making 500+ fwhp and 540+fwtq when both pumps were working.
Tuning has to be spot on though for it last.
My next step would be to move the fuel pickups to the bottom of the tank instead of pulling from the top.

or make a new tank all together. I'm sure you capable of doing it with your eyes closed

If you don't have rear seats installed and can handle the annoying sound of the 044, installing one here would help you greatly.

[Brad D.]

Wow, those shoulder harness straps are mounted at way to severe of an angle. That would be some spinal compression waiting to happen.

Sort of a cage, where else would you mount them?

[Brad D.]

That's why for several cars you can buy "harness bars". If anything, you might be able to rig up a mount to the parcel shelf area. Either do it right or don't do it at all.

I would never put fuel lines in the car.

I am not disagreeing with that fact, I was just curious as what you could do. I'm not sure i'd want to rig something up with the rear package shelf. Aftermarket for an e28... seriously doubt it. You could prob make a floor mounted bar that could go up and around (behind the seats). Where the seat belts could mount.

Like that mounted to the floor? I don't know if that could work or not. I also dislike the idea of having fuel lines in a car, I wouldn't do that. I mean if you didn't care about the rear seat the real way would be to build a proper cage, I want to know if you could bolt a bar on the far sides of the floor, come up to where the seatbelts would mount like in the picture, than inbetween the belts on the bar itself, weld 2 bars that would than mount towards the back of the car (such as the slanted part of where the rear backrest would sit). I would think it would be structurally strong, plus be a good place to mount the seatbelts.

.. or risk death by agonising fire. There are reasons for not having fuel or coolant lines running through the cockpit and why you have "firewalls" to both the back and front in racecars.

I'd put a catch tank in the boot, fed by the stock pump and have the 044 (or two) suck on that, return goes from fuel rail -> catch-tank -> stock tank.
You could have all the hardware under the car with lines running up to the tank in the boot. Make sure the feed lines to the main pumps are really large and unobstructed to make the most out of them.

No vids but

Two kill stories over the weekend.
Friday put on bigger drag radials MT 235/60/15 so went out for some traction testing
First race was a C6Z06 with headers, exhaust, CAI, tune. His buddies were egging him on to race me from a 60 so he finally accepted.
He beeped it off and we went at the same time, he jumped about 1/2 a car ahead but once my turbo spooled I reeled him in a passed him by 1 1/2 cars by 120ish. I noticed he was still on it so I stayed in it to see what the Z had up top.
He started to creep up and was by my door at around 170, by then I was at the end of fifth just under redline and let off. Ends up the Z runs 10.9 at 130 in the 1/4.

Second race Porsche 997tt with k&n and exhaust (so i was told) he wanted a 40 to 140.
First run we took off and I trained him by 6 plus cars, we got to the turn around and he wanted to go again, I said lets go.
This time the tires let loose and I got bit squirrely but stayed in it, the porsche was about 1/2 car ahead, once it hooked I pulled on him instantly and passed him by 120 and applied many train lengths on him.
Got back to the spot and he said he forgot to push the sport button on the first run, not that it made a difference anyway

I was very impressed by the Z06, couldn't even imagine how fast that car could be with a 200 shot

This sunday i'm up against a 06 Viper on spray 80-160, i'm going to turn the boost up tp 22psi and see what happens. hopefully I wont get beat that bad.

[T_C_D]

Awesome kills. I would love to see a slip from a 1/4 mile track with those slicks I sent you.

[Scottinva]

Wow that's really cool about the z06, knowing you can do that, and still be able to take it to autcrosses and roadcourses alike and compete. I see them doing all 3 darn good, what a cool car IMO. Great kills.

This car will not being doing any autox or road course events. It's a drag car.

It's a super light e30 with a big heavy lump under the hood.

SuperStock Z06 do ok on autocross courses that are fairly open.
In our area, good DSP cars (BMW 3 series) can beat up on them if the course not wide open flowing like a road course

Yea me too, but this street racing is too much fun
06 viper with a 200 shot is next on my list to race 80-160.

Peter thanks for fixing my Megasquirt

[Shadow]

Are you still boosting the same amount as you did
on your dyno?

[Good & Tight]

yes 17psi

[Good & Tight]

Raced the Viper last night, 06GTS with a 200 shot.
I turned the boost up to 22psi for this race, 80-160.
Viper beeped it off, I was in 4th so from the start he jumped out a car which I would expect from a 200 shot of nitrous, by the end of 4th I had pulled a nose then shifting into 5th he shifted also and pulled a car on me, 1/2 way through 5th I started pulling on him but then he hit the brakes.
He said we were at 160 when he hit the brakes, so I lost by a car.
Viper owner says it dynoed 650hp 780tq, car was very fast.
You win some you lose some, I lost this time.
