Those running the LT4 hotcam w/ N2O: need advice

Ok, I'm sure this subject has been beat to death....but I'm a newbie to N2O and know NOTHING about it. I have a stock bottom end with about 80k on the clock and I'm wanting to add a nitrous kit to the car but don't know what to go with (ie kit number, type, wet, dry etc) I'm only wanting to go with a 75 to 100 shot though and was wondering if you guys could recommend a good setup. Here are my current mods:

'95 T/A M6 (used to be an A4)
Stock thermostat
Stock injectors
No Air pump system
Moroso cold air induction kit
AS&M 52 mm throttle body
No CAT (straight pipe)
TPIS 1 3/4 shortie headers
LT4 knock module
Ported/polished MAF (removed screen)
Flowmaster Muffler
LT4 HotCam
Ported LT1 heads
2.00/1.56 Manley race flow valves
Crower Springs, Chromemoly locks and retainers Good to .580 lift
Comp Cams screw in studs and guide plates
1.6 GM Rocker Rollers
Flow as follows:

.100 71/62
.200 133/112
.300 187/157
.400 219/185
.500 248/192
.550 258.5/193.5

BTW, any guesses at what a 75 shot with the above mods would put me at HP wise or 1/4 times?

Thanks for any help! :bow:

I dont know what your car would do on the bottle but my 97 ss with a hot cam, heads, intake, long tubes, y-pipe ,borla and alot more with a 125 wet put down 460 hp 515 fp to the tires, not bad for the hot cam. I would get some nittos if you dont have them and spray that hot cam.

Thanks for the info! What kit are you running? Did you change out the rear end or is it stock? That was another thing I was worried about.


Thanks again!
:bow:

ive seen stock bottom end lt1's take 150 shots. my v6 had daily 100 shot. you will easily be able to take 100 shot. I would reccomend a NX wet kit. Its a awsome kit.

im running a hot cam with a 150 wet compucar shot with out any trouble, in fact im gonna step it up to a 175 shot :) you should be fine on a 150 shot, just dont abuse it :)

Back when I ran the Hotcam and a NX kit my car ran 12.30-40's@108-110mph N/A and 11.50's@117mph on a 125 shot regulalry. It put down 320rwhp N/A and 420rwhp with a 100shot. That cam likes some n2o. :D I would change the fuel pump for safety sakes b/c once I swapped cam, injectors and started making more power the stock pump couldn't keep up and burned up a headgasket and a piston on a 150shot.:mad:

I would say to spray it. I just put a TNT kit on mine. I also agree with T/A lt1, go ahead and put in a good fuel pump when you do it. I went with a RaceTronix pump.

I would not worry about using n20. I ran the hot cam and a NX wet kit all last year and loved it. It put down 346 RWHP & 345 RWTQ N/A and 475 hp & 499 TQ w/ 150 shot. It went 11.21 @ 122 MPH on the gas, and went 11.3 @ 126 with a 200 shot, this was a completely stock engine (minus the hot cam). I would definetly go with a bigger fuel pump. I didn't have any luck with the Racetronix 340 lph in tank, It failed miserably past 4500 rpm on a 150 shot. I think I may have had a defective pump, but try telling that to the guy I bought it from, so I just built a custom fuel system instead of dealing with that guy. The new system definatly gives me room to grow ;) I have a BG King Sumo 1000 LBH (aprox 670 LPH) fuel pump -10 custom sump, -8 supply, -8 y/block, -8 to each rail, -6 return to an aeromotive vac. assist regulator. My fuel system is the definition of over kill, and is not nessicary for your set up. A 255lph in tank pump should be enough.

Spray that car like there is no tomorrow. Hotcams love N20.

I have a hot cam/mild head(stock valves)/bolt ons and a 100 shot. I went 12.5 at 111 n/a (1.95 60') and 11.8 at 124 (1.9 60')on a 100 shot. This was with my auto in the car with stock suspension.

Another guy in my club with a hotcam/Lt1 third gen went 11.01 at 126 on a tnt 150.

Hot cam's are fine. Enjoy the spray and don't be stupid with it.

Hotcam has a 112 LSA :D

<-- I'll be spraying my Hotcam'd Z into 10s :p

Good luck with the 10's ZPaul2Fresh8, that is one of my goals for the year as well, that and low 12's NA.

Thanks. I ran 13.0 with stock gears/converter and damaged trans....

I'm confident 12.8 is possible with the new'r trans. With a 3000-3200 Vigilante & 3.73s, I'll be hoping for 12.2-12.0. But do we ever get what he hope for at the track?

My trans is being race built at the moment since I ruined something in it LOL...

Looking to skip 11s all together with a 150 shot :-D.

Hotcam and Stock heads :bow:

Oops was thinking of the CC305 for a second. Gonna edit that.

I think your times are attainable with good traction and everything. good luck.

I have gotten a 12.7 but I know there is more in it. I have added a new fuel pump, and an electric water pump so far. Also bought a laptop so hopefully I can get it tuned in right and get some good times out of it. I think I should be able to get low 12's.
