LMAO! That's

 

I was wondering the same thing

 

guys, im going to be off in the garage for the night, so keep this clean.

Robert is dry all the way, im a swinger. lol i run dry n my vett because it is less violant and hits softer so gives me a chance to hook. i run wet on the race car for that nasty hit and great even power.

both have good and bad points, bith have blowing **** up issues. not sure what up with roberts car, but like dave said blowing up or braking **** is never fun.

well, blowing my heads up and beating them with a hammer after was pretty fun, but besides that. lol

yea blowing **** up is never fun, chipping number 7 at 32k miles sucked, but i think im happier with my 402 i have now then i ever would with the stock 346. breaking **** is always an excuse to upgrade. but i know Robert blew his stock motor up, and this was his upgrade, so hopefully his new motor is fine. cause this hobby isnt cheap to keep buying **** and ******* it up.

 

Tttttttttttttt

 

I blew my personal solid roller motor up on the dyno with only break in miles on it and a 400 shot one year. I felt like crying. All that for poor voltage to the injectors...

Thank god I have never blown up a customers motor. That would really be hard to deal with.
Dave

 

I did not blow my new motor up, at least not yet. We have a dyno day shoot out Nov 24th and we plan on taking the top spot for sprayed cars, as we did last year, though I blew my LS6 up doing it in '06.

Now, on to the dry and back fire thing. Here's the still standing challenge, "Find anyone whom has had a DRY backfire on a properly set-up system". Maybe I have worded it differently on occasion, but this has always been the gist of it. This statement does not hold true for wet hits for various reasons. But as Dave said, this should not turn into the coveted dry vs wet thing.

OK, YES ROBERT HAD A HIGH RPM LEAN BACKFIRE. Why we might wonder, well when I got my motor back from Turbo Tech (by the way this is old news and was/is posted in the wet vs dry thread for all to see and never tried to hide it) it was surging (later found that the 1st stage nozzles had been knocked out of whack, on/off, on/off). So, and Ellis was there this day, we decided to abort the 1st stage and try the second, which at this time was only on a RPM activation switch, and it worked wonderful, so all seemed fine. Now the next time to the track, I swapped the 1st stage to the 2nd stage ws (rpm on only no high rpm cutoff), and 2nd stage was on 1st ws. I had it jetted for 145/150rwhp each. So then I make my first pass of the evening, and about the 1/8 mile or wherever, booom, sounded like a sonic boom. Everyone in the pits new it was I. Well what happened was, the spray did not cut off like it should and anyone who has had a noid stick knows the rpms stay up. Well this caused me to hit the limiter on a shift, and when the limiter is hit it pulls fuel, or shuts it down, and now we have the stage set for a high rpm lean backfire which I had at about 7000-RPM. Blew a hole in the back of the intake. Ellis, the TB and the MAF are both back on the car, it didn't hurt either one, just the intake. I am glad it was a dry backfire as the fuel vapors could have made it much worse if it was wet, IMO.

Anyway, Ellis ya better be packing Saturday, lol.

Robert

 

My worst motor $$ cost upon blowing a motor was a price tag of about 14k.

Robert

 

I will be packing but I am only gunning for the 650RWHP I need to beat you at the track

I only stated the TB and MAF after your own words Robert as you posted in the NW section. Sorry if the info I got was bad.

But hey at least it was not your pistons this time!

 

Robert,
Thanks for bringing me up to speed. Thats why I have always hated to see someone tune with nozzle placement a simple movement of the nozzle can be a huge issue.. If you would not have caught that you might be putting a new motor in there now.

We both agree that a backfire is more violant on a wet kit. But on any properly set up system a back fire is rare. Wet or Dry.

I use to have a buddy that was always just throwing dry kits on mustangs. He was always having some type of backfire. Just simply because he through it on there and hope for the best.lol

I am happy to here you did not hurt the new motor in the process. I had heard through the Grape Vine you may have blown it up. So I figured I would ask to see what happen.
Dave

 

Oh yea, you have me at the track for certain, but we will still try to catch ya.

I was just letting ya know the MAF and TB were fine. I did think they were the issue till Dr Phil sent me to a small area that is very hard to see and get at for a hole, which was there, hehe.

Robert

 

When NX first released the NXL nozzles we also Blew Tonys car up on the Dyno fighting the tune. We even had a NX employee standing there. Those things suck with big injectors. They pull a 3lb vacumme on the injector. We had pulled out so much fuel trying to get the airfuel right that we eventually just tore it up. That was a lesson learned as well.

 

That is the only two I have blown up on the juice. Thats because Tony and I have crappy luck with our own cars.

 

That's why I am excited about the new NX dry kit, much easier to set-up for all. Yea, those Fords and dry hits seem to have more issues than the LSx platform, I think it's a worse intake, or rather, an intake that is less conducive to a dry hit, and/or still some weak algorithms in the pcm.

The motor seems to run still great. What was funny, the new motor would still run, but wanted to idle at about 2800 rpm with the hole in it, lol.

Robert

 

Did you do a compression test to make sure all is well? That SS I bought the guy hit a 300 shot with 28 degrees in timing and no fuel pump. It took out the plugs but the compression test cheacked out ok he said. Well the third time I drove it the rod broke in half and took out the block. It was stock rods though. It must have bent it when it detonated.
Dave

 

Dry hits backfiring din't even hear about your car till this thread. Any pictures of the intake?
