How high comp. should i go with n2o on a street car on a b18c1??

 

i was thinking about squeezing a 100 shot on it also

 

Lotsa Fuel, High Octane, Timing Control, and Cold Cold Cold Plugs.

but how high can i go????? with the compretion

 

If I was building a nitrous motor....12:1

Suprdave

 

but with 12:1 and a 100 shot i will most likley be running c12 or higher then correct?

 

Yupp, you should always run the highest octane you can find...just to be on safe side.

Suprdave

 

well i always run 92-94 in my car i used to have a turbo integra GSR

what do you think about how it will run with a 2000-2200lb car with slicks? tunned with hondata?

 

i was thinking about 11:1 with a 100 shot with 2 deg retard on pump or is that too much or can i go higher?

Build it and lets see Should run 11s.

Suprdave

 

but can i go more then 11:1 with the 100 shot on pump?

 

Dope...I wouldnt even spray 100 on 93...your begging to get owned.

Race Gas is cheaper than a rebuild.

Suprdave

 

this is going to be with a wet kit and it is a dual stage also so it wont be as hard on the motor and my freind is running a 100 shot wet kit on his 98 GSR on pump gas

i myself will be going a 2 or a 3 deg retard on the ignition

 

anyone else has any input on this?

 

man thats goes against my friends ls nitrous setup cpmpletely.

stock ls longblock and tranny
head shaved the max
160 shot dry
255 pump
no tuning


12.4@108 with ls tranny.

yes it is, but his theory is the longblocks are like 150.00 bucks so who cares.

was that on slicks or street tires?

 

cmon steve, would i let a buddy tie my street tire time

 

I would stay away from a dual stage system for just a 100 shot. The more you can get in from the start the quicker the car will go (with slicks). As far as high comp. goes, I run 12.1 and I can tell you that the tuning window for staying out of detonation becomes smaller and smaller as comp. ratio goes up. I would also use race gas at least 100 octane or better.

If you can get long blocks for cheep I will take 2.
Let me know.

 

I have seen some V8's that run higher than the 12:1 comp ratio. Actually one was somewhere around 14:1 and he had gas on it. He ran a single carb setup on a 406 it was in a Mustang and it somehow managed to stay together. Its all in the tuning that car also ran 8.72 at 162 mph on drag radials.

 

you can run 14.1 I have some friends that run IHRA pro mod and they run that and higher. But the ring lands on v-8 pistons are twice that of honda pistons. I have learned that it is much safer to run a little less comp. and use more nitrous. I was running 13.5 on my last motor that did not last long. The comp. was not the problem I had the fuel jetting and pressure way to rich, trying to play it safe. I think that if the comp. ratio was a little lower it may have not lifted the ring lands so quickly. You can run high comp. but if you are not out to set records you should just play it safe.

 

so the 11:1 is going to be fine with the 50+75-100 then with rods
