I want to go with NOS as it is cheaper then turbo and electric SC is a waste of time
Question I have a Stock 2.4L Pursuit and want to know if you can go lower then a 50 shot if so what will gains be.

Also
Dry or WET
And what Brand would be safe

RPM Window Switch - what RPMs are safe range
WOT
a step or 2 colder plugs - what to get

 

wet, WET, WET. dry and you're just asking to blow **** up.

any brand that's got a model for 4cyl EFI will do ya.

RPMs 3k -> just before your rev limiter (6k?)
WOT switch as well
and an arming switch
1-step colder (srt4) plugs will do fine

 

I might consider 2 step colder just because of the stock CR, but again with out seeing your knock it's hard to say that you need them.

you could go with a 35 shot, but she'll take a 50 and 75 shot fine.

definitely want a wet kit single fogger. nx, nos, zex, nytrex, tnt, dynotune and a few others are all fine.

with your window switch, I would arm at 3200 and disarm about 200rpm before your engine's redline/rev limiter (I forget what the 2.4 stops at but I know it's higher than the 2.2). I'm running MSD 8969 with much success.

dont' cheap out on parts and don't rush your install and you'll be money

 

if you are worried about this you can always, get better valves Im guessing

 

better valves as far as what? why? you're fine with stock parts

 

Make sure its a wet shot!

 

Did not know,never ran the stuff myself,I just meant as an reassurance

 

ok, I just thought you had reasoning behind it like durability or resistance to heat like the LSJ sodium filled valves. not trying to pick you out but that was kinda random lol

 

even if I was to run nos, I would srill have the lsj valves or JBP only cause both are more heat resistant than the 2.4 valves

 

right, and that's a great idea, if they do in fact fit in there properly, but you don't need them, at least with a 75shot and under which is what the majority of people will run ever

 

it's not the n2o that raises the heat, it's the friction... you'd prolly actually do a better job with lightening the valvetrain with n2o

 

eh, the gain would be negligble though

 

I know Im runnin away with this thread, but with my valetrain job being done today what shot do you think I could run,not ever going to just curious

 

with the right precautions, and based off what you're sig says as far as modifications, I'd venture to say a 75 or 50 shot would run great on your setup (again, with the right precautions).

if you havea 2.2 I would suggest upgrading the exhaust manifold to at least that of a 2.0 or 2.4 to help flow out a bit, and make more usable torque in the powerband.

 

I have the 2.4 and my port and polish is being done today also,thanks for the info,never know come spring and the tracks open up,a little nos could happen,oh I did get the high heat performance vlaves

 

are you milling the head as well any? are the valves stock or high comp/flat faced.

 

head is being done and the valves are the JBP high performance/high heat

 

lol that's not answering my question but alright

you'll be fine either way, and I've heard good things about those cams in passing.

 

the cams I got no one has yet, Im the tester for JBP

 

I'm pretty sure they make cams for the 2.2 and that people rave about them

 

i think comp cams makes them for the 2.2 guys but not the 2.4

 

anyone know how big a dry shot the stock 2.4 fuel pump and injectors are good
for? I've had great results on my LS1 Fbody with a dry shot, wet is too dependent
on bottle temp (pressure) for AFR and I'd rather just let the MAF report the extra flow.
Intake was never meant to flow fuel saturated mixture as well.....
Also with a wet shot if the fuel noid fails- BOOM.....
I've always ran with an arming switch, FPSS, WOT and window switches as well on an M6.
Thanks
Mark

 

I would ask GTP on this one

 

The stock fuel pump should be fine, but you will be going over 100% duty cycle on the stock 24lb injectors. I bought some stock ss/sc 34lb injectors to slip in my 2.4 when I do my next round of mods (cams+.) I think i'm running pretty close to 100% dc with my current mods.

Go to http://www.rceng.com/technical.htm to calculate the size injectors you'll need for your intended power level.

 

Thanks, I'm willing to upgrade the fuel system if necessary but if stock can handle
a 50shot I'll go for it- one bottle and heater, good for 2 cars......
