I was curious as too what you run for timing on 200 + nitrous?

What is your fuel octane?
What is your timing?
How much nitrous (shot)?

Thanks in advance

116 leaded, 26*, 220 NXL Shot.
101/93 50% mix 24*, 175 Wet Shot.

I had my NA timing up at 33* w/o KR for the longest time, then began lowering it as the extra 5* didnt net me any gains, so safer to be lower.

22*
92 octane
on a
175, 185 and 200 shot and no KR, so far.

24* with a 93/104 mix, about a 225 shot at the crank.

Cat, what are you running for O2 sensors with the 116? Also, where you using TR-6s and how do they like the 116? Seems like they would foul running N/A.

Im running a 225 shot with 25* timing. I am using a stand alone fuel system for the nitrous with 116 octane in it. No KR or any problems yet.

How much timing would you all recommend for a 150 wetshot (TNT) on Pump Gas?

badls1

iTrader: (1)

150 shot and pump gas probably around 20*. remember that 150 is rwhp. Its like 195 flywheel.

O'dell

Yeah I realize that, that's why I stated it's a wet tnt shot. I have access to race gas (55 gallon drum in garage right now actually), and will more than likely use a race gas/pump gas mix on the 150 shot just for safety since it's still stock block, was just curious.

well i have the same setup as you do on 200 shot straigt f&l 105 and cant run more than 22*. but then again every car is diffrent. mix them toghter half and half. change your knock retard from 4* to 8* (to be on safe side) run 25* timming and see what happens.

Normally on a 150hp shot and lower no timing needs to be pulled on a stockish car. Should log to be sure.

Well I have Heads/Cam/ and all the bolt-ons, plus it's an auto . The heads aren't milled, but they are CNC ls6 heads.

I think 20* is way to low unless you only run 91 octane. or something. For a TNT 150 shot I run 24* on straight 93 octane. I've never had a problem with detonation. At 26* I would start to pick up 1-2* of random KR.

I agree. I run 22 down low, and 24 up top on a TNT 150 shot. I consider this to be a very safe tune. My tuner said I'd probably be fine w/ 26 if I wanted to push it.

Harry, how is it going?

Remember the F4 kit you sold me? Check the pic below for what that intake looks like now
Anyhoo, did you ever find the relays for the kit?
thanks

I think i seen one of them. they are 30amp realys like $3 each you could get them from any auto parts store.

That manifold looks nice. I missed my old combo. nothing comes close to it. since the turbo is taking some time, i am running my friends tnt f2 kit.

did you get times out of your set-up yet?

No, I got screwed out of my motor =\ I am still building it so it's taking a while. I didn't know the relays were that cheap, heh. Also, you had the F4 jetted for 200 when you shipped it right?

i belive it was 225 check the jet size or let me know the jet size and i ll get you the hp rating.

I get bosch relays for 2 dollars a pop. That kit was jetted for 225 shot. I would switch it to a high pressure inline bosch pump. The low pressure pump has too much variation especially at altitude. You would also need to swap to a high pressure regulator. It will make it much easier to tune. Money well spent imo. A lot of time went into making that f4 kit.
