Broke my Gen 2 on a 40 shot

[whtrthanu]

i have 100 shot on a BONE STOCK MOTOR!!!!!   it hasnt broke yet....I know i will torch a valve soon enough...but you guys aint tuning right....STOCK PUMP STOCK INJECTORS!!  mapped thru the ecu.... you need to set the spray bar up right and make sure its evenly distributed.....the stock fuel system is fine to over 300hp greg smith has proven it plenty......
GOOD FUEL AND A GOOD TUNE UP!!!!!!   these things have 12.5:1 compression stock!!!!!  they almost detonate on motor already.....you add some spray and your fucked.....

by the way, that set up is sweet draco!!!!!

I don't doubt that people (including myself) have gotten big HP numbers on the stock pump.  But the fact is that the stock pump was designed for a 190 HP motor.  Unless you log every pass with a logger and watch for the pump to go soft, there is a very serious risk that you will blow the motor when the pump pukes on you.

Ehhhh, wasn't the nitrous at all. Looks like the "builder"  didn't use the proper base gasket and the pistons kissed the head.

There you go, problem solved, I'm still going back to stock Gen 2 rods and pistons.

Gonna work my game and get it to run a consistent 9.3* and just be fucking happy with that. I only go to the strip 5-8 times a year so it will be fine.

Btw, lots of good info in here.

Anyone interested in bottles, ECU setup for spraying and assorted other crap to spray?

50 cents on the dollar for it all.

Out of curiosity, what size bottles and how much?

I've got the same set-up and had to go with a .125 spacer.  If you need stock rods and pistons I have the rods and can give you a great deal on them.  If you want mine send me a PM and pick your price.  Good luck bro.

Sorry I haven't responded. One bottle was from http://www.dynotunenitrous.com/store/Scripts/default.asp with a gauge and the other was a local purchase from the "builder".

I would let them both go with gauges mounted to the bottles for $150 shipped.

One is a 2lb, the other is a 2.5lb.

Sorry for the slow response. My wife is in the ICU with a broken back. Been a little busy with that.

Thanks for the offer. I still had the stock stuff and it is all back in the bike. It is running really well now.

I feel your pain. I floated a valve and spit a shim on the first trip out with a well tuned 40 shot. I went with s/s valves and 65# APE springs. I bumped up to a 48hp shot with a crushed regulator and a tune with the Bazzaz auto tune. Something is wrong now after 50 or so passes.. I ran 146 on the spray. Maybe its just clogged .018 jets. Its a Spider kit and it uses 4 jets. It has happened before. If they look clear I'm doing a compression test. We will see.

Good luck. I took my bike back to the strip last Friday with the motor back to stock specs and no spray.

Lowered on the second hole with the front slid up an inch i went 9.50@150mph. Not to bad at all I think.

If I can get my 60' down from a 1.6* I will get the ET where I want it to be.
