Ouch. If that's the case, he must have run into some issues, obviously.

 

Oops 13.2!!

 

wow i'm glad i didn't go up. 13.2 would be epic fail. I could prob run that on my street tires. Hell, I just might go up and do it now.

 

Well a 12.9 was the best I managed on the third run. On the 4th run I went spray and broke some ****. Possibly a methanol backfire as I hadn't turned the switch on for nitrous yet:

 

hmm... wasn't expecting that to break... of all things

 

Yeah I knew the bottom end was strong, guess I found the next weak link! Lol.

 

I said "ouch", but I had no idea... Double ouch.

 

dayum.. :|

What mix meth are you running to get a back fire out of it?

 

Very odd to see it backfire like that. What RPM does it start spraying meth at? Faulty control box maybe?

 

Ouch. So that's what a nitrous backfire looks like.

 

nope its not

 

Sorry, Meth Backfire. I didn't think Meth could do that. You sure you weren't spraying Chris?? lol

 

Wow thats odd that that would break lol

 

12.9 off the nitrous, hmm. me thinks those slicks had something to do with it.

Goddayyum @ the meth backfire. Destroyed that intake manifold. Lucky it didn't **** up the supercharger. Just the bypass valve.

 

lol you go z06 killer!!!!

 

 

When there's more methanol than water in the mixture it becomes explosive. The more methanol that's in there, the lower the temperature needed to ignite it. Especially under boost. The switch was off for the bottle, I think it would have done worse if I was spraying when that happened. I'm just gald that's all it did lol.

Yeah the slicks and the air struts with chains in the rear made launching a breeze. Without even taking off hard I was able to pull 1.9 60s.

I knew as I was driving home it was either the throttle body or bypass valve. I checked the rotors on the blower though. They still look brand new lol. This thing is a champ, even with the bypass bent wide open like that it will still make 5 psi by 4000rpm lol.

About 80/20. And you guys wonder why I harp on the 50/50 mix with the hotter stock blower.

When are you and I going to race? I make about the same power you do in a car that weighs about 800lbs less. I really wouldn't talk lol.

 

Ok there killer, nice 13.2

 

wow that's interesting, I have never heard of a methanol backfire before. I am going to research up on this and see how common it is and how exactly it happens. I have sprayed a fairly high mixture of meth with extremely high iats and iat2's and still have never had this happen.

Are you thinking about backing down your methanol mixture now to save problems from occurring in the future?

 

Lol, orly? Not the only one with a power adder, let alone your two.

Still a couple seconds faster than you chief.

 

It was a 12.9, here's the slip. Car 005. And a pic of my car for reference to the car number.





Nope, not backing it down. I think it was a fluke and possibly the bypass valve not opening in time. I mean I hit like 24psi when it happened lol. Methanol can catch fire in an intake manifold, don't let anyone fool you lol. That's why they're required to sell "methanol injection fluid" as a 50/50 or 51/49 mixture.

He's A second faster than me off the bottle even. On the highway that goat would be in my dust.

 

With that silly 108 trap, I hightly doubt anyone would be in your dust on the highway. Besides, rice racing is frown'd upon.

Dyno 400+ to the tire, with two power adders... The best trap you could come up with is 108?

It don't matter how much traction you have (1.9 is subaverage with those tires), that is sad.

 

Lol I wasn't even spraying at the track. A 108 trap with a 12.95 on just 321whp/265ft.lbs. isn't too awful if you ask me. Do you know of any other LSJs making over 400whp, still running, with just ONE power adder? I can only name three lol. Also "on those tires" I was spinning at the track even. PRP just plain has shitty track prep. They only respray just before all the "fast" slick cars run, right after all the street cars have ran. And if you're going to go by trap speeds, I can name vehicles that run a 12.0 at the track on just a 108 trap speed. I guarentee I waste them rolling though.

 

I've seen, in person, the poster above you run 108mph in the 1/4 with a 2.5 on stock blower, on stock pirellis at PRP. I guess thats no power adders?

 

I dyno'd 255whp and was running 13.4's and trapping 110mph. Also getting 2.0 60's on OEM tires.

Only had ~500 dollars into the car at the time as well. 2.5" ring, 60#s, intake, and Tune.

This was before PRP went NHRA and prep was even worse. Let's compare the amount of work, modifications, and money into your LSJ compared to my old car.

I've also personally seen a TVS car with your same pulley, trap 113 with a bad set of coilpacks and letting off half way in third because of the misfires. Let alone what it trapped with good spark.

I am not trying to be an ******* (okay, I am), but something is clearly wrong.
