Go or blow

Big shot plate , Induction solutions 120 orfice solenoid , 110 nitrous jet and 95 fuel jet 5.5 psi fuel pressure and total timing at 16 degrees , 562 with 14 to 1 compression #11 ngk plugs sonoco max nos 116 fuel
284- 298 @.050 or 114 lobe sep  , you guys think this tune is safe ? This is the biggest jet I've ever tryed , need all I can get this weekend, heads are tfs standard valve location cnc 325 cobra jet style heads

Yea it looks safe. I'd put a -10 plug in it though

Just asking but why #10s instead of 11

11 too cold, id start w a smaller fuel jet tho, maybe back timing down a degree or two more also

I got a 93 fuel jet that would be a 17 spread
And you thinking 15 total timing or even 14 ?

Id want a 20 spread at least, the timing isnt far off id just pull a couple extra to be safe and sneak up on it

This.

Well.... What did you end up throwing at it? Did it break other folks hearts or just parts?

Race is today , but it's looking like it's going to rain

Keep us posted!

100+ HP .047 to .052 nitrous jet with a .010 to .012 smaller fuel jet
150+ HP .062 to .066 nitrous jet with a .012 to .014 smaller fuel jet
200+ HP .074 to .078 nitrous jet with a .013 to .015 smaller fuel jet
250+ HP .085 to .089 nitrous jet with a .015 to .018 smaller fuel jet
300+ HP .098 to .102 nitrous jet with a .020 to .024 smaller fuel jet
350+ HP .116 to .120 nitrous jet with a .022 to .026 smaller fuel jet

On average these tunes even starting at 6.5 PSI FLOWING if properly timed are good starting points. We also ALWAYS flow through the same .073 fuel jet. Here's a little read that can also help you better understand why..

FOOD FOR THOUGHT!!!!

update

Rain out

we got rained out Friday night as well 0% chance of rain is what they were calling for

update

Saturday the 18th

Update

Update ,  there was no 10.5 race , the whole race was a cluster f**k , the most Un-organized race I have ever been to , all the 10.5 racers split the pot and loaded up , we drew numbers for the 1st place trophy , I won the number draw , I never made a pass

Sry to hear it was a cluster... at least they didnt screw you out of the pot split, and if it is any consolation...not many people can say they didn't even have to unload and the gave them the 1st place trophy keep us posted when you find a track to let er buck!

Update , I finally got to make a pass last night , 110n and a 93f jet , total timing is at 15 degrees , fuel psi is 5.5 , plugs look clean , but the heat mark on the plugs looks like it needs a little more timing pulled out , next pass I try will be at 14 degrees , this was with a #10 plug
Ran a 5.25 with a 1.19 60 foot , this track is not prepped but a few feet passed to 60 foot mark , you can feel the can spinning on the big end

Nice, how much did the car pickup, and did you get any video to see where and how long the car was unloading the tires?

No video , but the car on this track and 275 shot went a 5.43 that's a 95n and 82f jets
I also took a 100 pounds off the car since

Hard to tell how much it picked up without knowing how much wheelspin was incurred, the 100lbs is up to a tenth, so it did pick up but it will pick up more when it stays hooked up. Hook is a major taxation on the numbers, looks like your travelling in the right direction. I find video really helpful on the suspension tunes as well, weight transfer and wheelspin are easier to pinpoint.

Nice run. What kinda mph did you have

Who knows , this track don't have mph , it's not a good track, it's not prepped well , my brother runs in the teens at a different track and in the 30s at this one when he makes a good pass , what I'm saying is it takes a well working car to make a full pass.
