Guys running hot cam and Nitrous read

Just wanted to know how the car is doing with the bottle and cam and what size shot you are running.

I have a Hotcam in my car, except its on a 110 LSA instead of a normal 112. The 112 is better for nitrous though. I am spraying a wet 100 shot and I havent had a problem yet with it. The car responds well and pulls like no other.

Mine is running fine as well. I finally got my tranny redone and am taking the bottle to get filled and dynoed again in the a.m.. I've got a 3200 vig and with the additional 100 shot, it pulls like a s.o.b.

Getting car tunned tomorrow, but I've been spraying a 75 wet shot and doing fine.

The Hotcam is real good all around cam for street cars. My Transam ran 12.30's@110mph with a Hotcam kit, AS&M midlengths, 2800 Vigialnte, 3.42's, boltons, mailorder tune and some ET tsreets. With a 150HP NX the car ran 11.40's@121mph on pump gas, driven to and from the track. The car was my daily driver and I made a ton of passes at the track and the street before I to go 11's N/A and 10's on n2o. It is totally doable with the Hotcam but when I had the heads ported I decided to go with a bigger cam too. Now I am in the process of putting some Trickflow heads and a Victor singleplane intake. The speed bug never ends. Goodluck. Later Clint

what kinda plugs are you guys running ??? anyone running stock type ac delco plats ??? I was thinkin of regapping mine to .035 for N20

It is never a good idea to run platinum plugs with nitrous. The extra heat generated will melt the tip and blow the puck off the plug. I am running Autolite104's and i like them, others like to use the NGK-TR6's.

Getting car tunned tomorrow, but I've been spraying a 75 wet shot and doing fine.

Do you have any timing pulled??

I have autolite 104's and they have been workign fine for me

I didnt think plats were a good idea but im getting ready to put new ones in for my delteq and new header gasket install. N20 is at the least months away so I guess Ill just wait.

Do you have any timing pulled??

just what was with the mail order tune, and honestly I don't know if it's different from stock. Here are some numbers for you though, car was tunned yesterday. Remember this is with stock unported LT1 heads.

341 rwhp 349 rwtq N/A

407 rwhp 441 rwtq w/ 75 shot

439 rwhp 497 rwtq w/ 100 shot

didn't pull anytiming before or after and car was fine, didn't go lean. Hope this helps.

Those are some good numbers...pretty much mine to a TEE! Except I have LE2 heads...I figure that the 2* is killing me. I am getting it retuned tomorrow and then dynoed. I will post tomorrow afternoon. I am just going to do a 75 shot, so I think killing the timing will be fine since I don't use the nitrous all the time. Here's my graph with the screwed up tranny and 2* taken out with and without the 75 shot. http://community.webshots.com/user/redr8er58
Let's hope it turns out better tomorrow!

he didn't tune mine for nitrous, but it could do better with plugs and tunning, it was a bit lean, but not too lean.

In a '96 Vette through stock exhaust (116K cats as well) and an LT1 to LT4/Hotcam conversion, 2800rpm stall and TNT nitrous setup I put down 422RWHP (DynoJet).

Fuel pressure at 50psi, TNT 75hp fuel jets (dual .018) and 100hp nitrous jets (dual .039), bottle at 950psi.

NA it normally put down around 305RWHP (DynoJet) converter unlocked.

A/F on nitrous was a pretty flat 12:1. Perfectly safe.

Am running NGK TR-6's at .038 and using LT1 Edit to pull out 3 degrees of timing above 4000rpm (which really isn't needed). I could probably gain a few RWHP NA and boosted with the normal timing. But it's a toy and I like it to be available for abuse.

That was a year ago. My setup is a bit changed now ;) .
