Well then.My 1st question is,,,what is the max intake manifold air temp before no gain will be realized.So far I have seen 205* in the intake.This is a Roots set up,wonder if it's different for turbo. shruggy

I'm getting ready to dyno tune my new 511" low deck this week or next. A few questions:

1) Should I use an inline nitrous filter?

2) Plug gap?

3) How do I purge the fuel solenoid? Through the engine with the bottle turned off?

4) At what RPM should I hit it on the dyno? 5k?

5) The designed max RPM on this combo is 7500. How high should we let it go with the nitrous? Don't worry about my stock block I had it blessed by a holy man.


beats walking!

I like to see very timing sensitive smallblocks set up in the .080 range for a lot of nitrous

You nitrous solenoids should have filters, if you bought a kit. Do you fill your own bottles, or have them filled. Most guys who fill use a filter in the fill line to avoid possible contamination in mother bottle. So if this is done no need for an in car filter......But, if won't hurt to run an inline filter.

Plug gap .020-.025

You shouldn't need to purge the fuel solenoid, but if you feel you need to, turn the pump on, crack the line and then retighten. Without engine running of course.

4500-5000 will be fine on activation rpm. If you plan to turn the motor to 7500, that's where you should go

Thank you for the info Monte. Should I run the engine on pump gas a nitrous fuel supply on c12 or both on c12? I have been dreaming up a slick partitioned fuel cell that would allow two fuel types.

Jeremiah...what I've been doing w/ mine is running it on straight C12 when I spray it. I do trailer my car to the track, so I drain the pump 93 out and refill w/ C12 at home. My motor is around 11:1 and I'm spraying about 250 on it.
I didn't want the hassle of 2 fuel systems...I did that several years ago w/ this car and it worked ok, I just wanted to keep it simple this time. One big pump and a bunch of regulators, lol.

I am not a fan of mixing fuels, so I would rather run it on one or the other

You guys spraying a pump gas engine do you ever spray with 93 pump gas or are you always changing out fuels for the track...Smallblock at 9.5 comp !!

I've never sprayed on pump gas. Not worth the chance of hurting something to me. It is a pain in the rear to drain the tank and make the switch before going to the track every time, but it is what it is.

Turbo Guys: Ever give any thought to an electric WG actuator?

I guess the way most handle it now are with compressed air and electronic boost controllers.

Many OEMs are going to electric actuators for WG control, as it allows more flexibility (i.e. opening WG at part throttle for increased fuel economy).

While we are not interested in fuel consumption, the flexibility this could offer might be interesting, during staging, etc. I can't help but look at the actuator on my desk and think about adapting it to an external WG.

I guess no sense in reinventing the wheel, but just thinking out loud...

Thank you all for the responses. I'll stick with straight C12 with the n20 and put a drain valve on one of the sump outlets.

Nitrous question.

My car runs 10.45 to 10.50 N/A. The BO time in the class I run is 10.10sec, so need to gain about a 1/2 second. It´s not allot, but its still about two car lengths at the finish line, so.. I don´t know if I´ll be able to gain the needed 1/2 second just with chassies tuning (Cal-Tracks, AFCO DA shocks front/rear) and going with a taller slick tire. I ran with a 29.3" diam. Hoosier QTP tire, going 30x9" Hoosier slicks this season. 60ft times kinda suck, got the 60ft down to 1.51sec, but haven´t been able to get the car off the line with out tire spin. I hope with real slicks and some chassies adjustments I´ll be able to get the 60ft times down around 1.45sec. (Hope it would run a 60ft under 1.45sec.)

I don´t think I´d need much nitrous assistance, something like 75hp shot should get me where I need to be?

..any ways, to my questions...

1. Do I need to run higher octane fuel if only adding some 75hp of nitrous? (The engine has 10.8:1 comp. I run on 98oct. pump fuel, don´t know what´s similar in the Usa.)

2. Should I run a separate fuel system or would I be able to run a 75 to 100hp shot with 98oct fuel, just by adding a second regulator for the nitrous fuel feed? (Run a Magnafuel 275 pump)

3. How critical is the carb tune before adding nitrous? Right now the carb (1050 cmf Dominator) runs on the fat side. At full throttle the A/F is around 10.4.

4. How much timing needs to be pulled if adding 75hp shot of nitrous?

5. Should I forget about the whole nitrous deal and just focus on getting the car off the line and get the carb tune better...

-Sorry if my quesions seem dumb, but Im new to nitrous so... I´ll probably have more questions later...

Thanks!
/Tom

I am in the same boat as TomsCharger70. I run 6.20's in the 1/8 and I need to pick up around 2-3 tenths to run in my local 6.0 heads up class. I was thinking around trying the same amount of NOS as him. I am also on pump gas but 93 octane. I need the same info as him.

Always on pump gas, as it is a street/strip ride.

Gary my sons magnum 360 (all stock except for camshaft and carb intake) runs fastest on plain pump 93. I proved it to him we swapped out 110 race gas and it picked up almost .2 in the quarter mile.

I was spraying a 200 shot on a 408 small block magnum with 10.2:1 compression and 93 octane, drove it to the track running 5.80-5.90 all day and then drove it home.(1/8 mile times)

Got Eddie Miller building a 410" small block magnum with 11.5:1 compression and will also be spraying a 200 shot on 93 octane in the near future.
