I am going with a baby cam for my set up plan on spraying a 150 shot. I am in between a tr 224/224, tr 224/227, or the tr230. I really want to go with the reverse split since i'm doing cam only , but dont think its going to react well with the spray (even if i back it down to a 125 shot). My stall is my limiting factor , i'm running a pro torque 3000 stall so on spray my guess is it will flash to 3400-3600. I'm thinking in general the tr230 might be a tiny bit to big for the 3k stall, and dont think right now its worth upping stalls to a 3400-3600 i'll wait until its rebuild time. Oh yea plan in hitting the spray at 3k, and down the road intake and heads but not till next season

 

well i am not an expert but i can give ya personal experience with this question. I have always read and been told up to 150 its fine pick a cam for what you want on motor.

I personally ran the tr230/224 with up to a 150 with no problems. I was six speed and stock rear with stock gears at the time and went an 11.14 @ 124 on the 150 shot (zex kit). so i wouldnt by pass that cam because you mite spray, it does alittle better than you mite think. Oh n the car was full weight dd then also.

 

i too would like to hear some thoughts on this. I've heard reverse split cams don't get along with nitrous as well as other cams. I've got a TR230 sitting in my room, and want to add a 150 shot to the mix.

 

I have a H/C TR230 car and dont have any worries about running nitrous on it. Plan on running a 150. You dont even have to consider cam profiles till a 200 shot i believe. 150 and less you will be fine.

 

Well my cam is a 232/228 574 571 113 and im hitting it with a 150 and making 570/540 to the wheels if that answered your question.

 

The question isn't will the car make any power with nitrous and a reverse split......but does it react well. Nitrous will inherently make any car look like a champ on the surface, but is there a better setup to be had as opposed to a reverse split.....then the answer is yes. The nitrous will definitely benefit from a traditional split cam. The increased exhaust duration is beneficial, usually in fairly substantial ways. Find you a good traditional split...you will make all the power you want NA and even more on the squeeze.

 

I agree, and a little more lift on the exhaust side also, imo.

that being said what if you are running a car with true duals so the exhaust flows very well would you benefit with a little more on the intake side. Looking at a 224/222 .609 .581 112+2

 

I would go for the TR230/224 if I was you man, you aren't always going to be spraying and your verter isn't too small either. The TR230 is a very docile cam that makes great power, both under the curve and peak and would be my first choice for a DD car. Are you running the stock 2.73 gears? A quick swap to some 3.42's coupled with your verter and the TR230 would be perfect IMHO, especially on spray

A while back there was a guy that went by the name JuicedSS262 running a TR reverse split, spraying a dual 200 shot and he did rather....well Do a search for some of his videos etc.

 

he has 3.23's i think..

 

Duuuurrrr, he has an SS. Now I feel like a D/F

Anyways, I still stand behind what I said. I think the TR230 is perfect for what you're looking for.

Edit- if you're still looking for a medium sized cam but in a traditional split, I'd take a look at the SI5 from Speed Inc. It's a 231/237 .589/.595 112 and would work rather well also.

I would suggest going with something that has a nice exhaust split. We have a couple of small to medium sized camshafts that are spec'd for nitrous. PM me if you want more information. Your converter is going to flash higher than 3600 depending on the STR. My Yank 3600 flashed to 5400 on a 150 shot.

it's not that a reverse split and nitrous "don't get along", a reverse split just isn't the most efficient way to do it. hell, you could spray a 350 with a reverse split and not have problems, but it's not the optimum way to do it. the reason the "after-xxx-shot-you-have-to-go-standard-split" rule of thumb is because when you get to a certain level, it just makes more sense to build your setup to be either a nitrous setup, or more of an N/A setup with a little juice for fun now and then. it goes along with the old saying "you can't have your cake and eat it too". at somepoint you have to choose a side...it's kinda like when you go to the store and there's three different aisles open, but the line is so long that everyone's just standing in one long line...at somepoint you have to make a decision and pick which cash register you think is gonna be the best option for you...

cashier #1 - daily driver that only sees spray every once in awhile...

cashier #2 - not DD, but still sees alot of street duty...

cashier #3 - dot daily, not much street time, sees aloty of track and probably alot of n2o...

 

tr230 would be nice if i had a bigger stall. A 3k and a 230 wont be optimal. I'm setting the car up for n/a cause really the amount of spray i will be going with i wont see to much of a difference. I realisticly with my small converter has to stay under a 224 to stay optimal. Yea i could run a monster cam but really wont be gaining to much. chad i'll give you a call when i get closer to ordering. Have to catch up on some unexpected bills first

 

Here's the reason we need more help on the exhaust for spraying, more exhaust gases to get rid of. Meaning, we are not putting anymore air into the exhaust tract, but we are adding fuel in the combustion chamber to work with the added oxygen that the N2O produces once it gets hot enough. so bottom line, we now have 3 times as much exhaust gas compared to n/a, and thus the reason for help on exhaust side. What happens when going bigger and no work on the exhaust side, the combustion chambers turn into furnaces and detonation/melt down can occur, ask me how I know, lol. Standard for duration and lift to be addressed for a nitrous cam, and even for n/a.

gotcha my thinking was since i have ls1 heads and ls1 intake my intake side is hurting so the lack there of air and a little reverse split would run like a standard duration on a better flowing car lets say an ls6 head and intake car. Figured with long tubes and true duals the exhaust flow is better then reg cars with a ypipe and catback. Setting the car up to run good n/a and with a 150 shot at max will be setting, but 100 or 125 for now due to the lack of fuel pump.

 

I was in your same postion about a month ago. My car had basically the same mods as your's but i already spray a 100 shot. So i wanted a cam that would perform well n/a because i don't plan to spray very often. I was also leaning towards the tr230 because it is a good performer but i wanted a cam the would perform great on and off the bottle. So i decided to have patrick g spec me a cam. We decided on a 230/232 .612/.595 111. We both think this cam will perform well n/a and still be optimal for the bottle.

The cam came in and it was a little bigger than it was suppose to be but of course i didn't mind
So my cam is 232.13/233.86(basically 232/234) .614/.593 111

This cam should be an all around performer and meet the goals i have in mind. I think custom is the best way to go when you can't decide on a cam.

 

I know this is an old thread, see I can use the search button

I am doing a H/C/I swap andhave the TR230 cam. I am going to spray 100-150 on it, the bottle won't be used that much.

I don't really know why I am spraying it. I guess because I've never messed with it before and want to see what it's like.

I went with the TR230 because of low-mid range so I don't have to spin the **** out of it.

Anyone else have any experience with reverse split cams and nitrous?
