What's wrong with this picture?


It started melting the exhaust valves too:



Just a 75 shot on a D15B8/Y8 Mini-Me. Tuned with 11.0 AFs (91 Octane) on Neptune. Didn't like it very much.

what plugs did he use tho?

I don't think it was the plugs. I think it was too much timing. Nitrous engines tend to prefer little advance, and using the Y8 head with flat-topped D15 pistons produces a VERY efficient combustion chamber set to burn VERY quickly without the introduction of nitrous. Tuning off of stock D16 tables woud already have too much timing, even with a few degrees retard most people seem to give a build like this. I would have been curious to see the spark plugs after a power pull NA. I would bet it showed too much timing for the engine.

Too much timing, no matter HOW rich the engine is, will cause problems.

Just do it, bro. Get a good fuel pump, injectors, tune and roll out!!! I think it should hold. That would only be about 175whp probably (give or take). Why wouldn't it hold that? That's like everyone saying that a stock d would only hold 200whp,that was untill someone made 300+ safely on a stock z6 with head studs.

He was using NGK 7ES-11s gapped extremely tight. The tune was not based on a stock map, it was made from scratch by a professional tuner who has experience building and tuning 750hp Honda's. It was a VERY safe tune. The timing was retarded enough that the car couldn't hardly idle when cold. Even the bottle pressure was very low that day.

Exactly!! Have fun. Just find someone near you that chips and tunes on crome or something similar.

Death smoke.......yeah I know what the exhaust smoke looks like when you are burning it down........I have the pistons to prove it!

Bigger, Better, Faster.

z6civicex

bones i think im gonna have a piston to start my own collection now! and yes bigger,better,faster this time!
