Ya, it cracks me up when a guy burns his stuff up and when asked what his bottle pressure or fuel pressure was he gives you a funny look. I have a buddy that runs a VW with a .40-.046 jet in it (50-65 hp per cylinder!!) he has nipped several plugs....the guy does not even own a flow tool
I am waiting for the big melt down.
05' season burned up three engines , it was making me crazy...sold it.... ,built another ,burnt it again--found out ,there was a 82 jet #7 cyl. instead of a 32?????? the 32 was mislabeled,think how much i was learning about nos? 06' no failures,aprox. 50-70 passes-everyone on a 500 hit..no freshen up still going to use it in 07'

I disagree with you on this with any car less than a Pro-Mod (I have no experience with cars that fast) but with cars in the 7.0 range and slower one big pump is safer. What if you forget to turn on the fuel pump for the nitrous, or if one of the pumps for whatever reason dies?
Gotta have two pumps ...wire it so u cant forget...the pressure for the nos has got to stay the same and if u have two syst. it will change again...it will work w/ one and keeps it simple, your right ,but soon as something happens u will second guess that single pump.Call nos ask them..they say 2...although I would love to run 1...theres one negative to nos ---Not Enough Fuel

I have heard of that happening. I check all my jets very carefully before I install them. Now all the good jets are stainless and are much higher quality.
How long did it take the motor to die? Having the wrong size jets is one of the most frustrating things to deal with because you can not feel the motor dieing, no popping, no surging, just piston death.

Well it something you don't forget turn on,if one quites,somethings getting messed up.On a PM I don't know of a pump that supply fuel in 2 places at once and still supply enough fuel for 2000hp.
My 37 ford pro street car had to fuel systems.but it was 1600hp on the bottle.
My 94 z28 and my 69 vette both run one pump to supply the fuel and nitrous.But we are talking 700-800hp on the bottle.

If I had a Pro-Mod it would have two Magna Flow 500's or two PE 460's. I was talking about cars like Oliver's or mine. Even with my next motor combination probably being capable of running low to mid 7's I will run one Magna flow 500.

I don't think that mine will ever run 7's.. Anything faster than 8's is a lot more expensive... I think that my car will be tough enough to handle 8's with a racing block and a spool in my differential.. Of course I'd have to upgrade the chasses to a full cage and the tranny to a built glide... but other than that, everything should hold up!

My 37 ford was in the same group as your vette.In the time's department,If your running a plate system it may worknot saying it won't)but if you go to a fogger set-up,I see where one pump would work.
I have never used any other fuel pumps than Aeromotive so I don't know if there's any differnce in there flow #'s.My 94 z28 and 69 vette has one pump,but I run it to a y then it goes to 2 regulators,one for the nos and the other fuel,it works well and you can run each set-up differnet.

The engine lasted 3-6 passes,I tried everything to keep them goin ,at the same time learning more and more and actually keeping alive longer as I kept rebuilding the engines...THEN I found my problem...

That's the #1 think is you find out why,I don't know how many guys I have seen do the same thing engine after engine,What most don't realize is the nitrous the more timing retard it take's.
To bad we don't live closer I would love to hook up with you guys.

I would have guessed it would not have made one lap. That one cylinder must have had about 200 hp worth of nitrous going to it. I have never run a plate or I would know.

Step one done---car went to frame shop--They say it was straight and only needed alittle adjustment..next step ,body shop ,no paint--then chassis shop,straighten out suspension, trans getting freshened up. after engine and trans installed, back to body shop for paint. Then Virginia..lets race , who's comming?????????????Can't Wait to let that trans brake rip
C3AV,
Do you have any pics of the solid axle/4-link setup?
I met Vettemaniac in Houston today to return his carb (Thanks Nick) and to buy the L-88 fender flares that he was not using. We met at the shop that was doing the headwork and they were finished. He said his 638 was at 427Hotrods' and things are ready for assembly and then to the dyno in January.

I'm thinking about building a outlaw 10.5 car for next summer,if I can talk my wife in to it,My PM ride wasn't working out so I left that deal(racing with a friend).I have a 66 vette body,or I kinda want to do another street rod style car,(32 ford,34 chevy) when I told my wife I wanted to do this,she said why did we sell the 37,I said after 7 years it's time for a new ride.
Anyway I would love to run some of the 10.5 race's at ATCO,but that's a haul for me being in missouri.
