Looking for info about this. . how will a 4k stall respond with 100-150 shot? Would it be too much with the stock rev limiter?

 

Nothing a retune wont fix. Havent seen many people run a converter that high with nitrous in a street car.

 

I wonder if the converter will flash too high?

 

it depends on what the STR of the converter is how it will respond to the nitrous. but if you dont go over a 150 shot it shouldnt blow thro too bad. you need to talk to the converter manf. and tell them everything about your combo and your goals. they will set you straight on what will work best for an intended purpose and get you real close...

 

I'll definately talk to the manufacturer as well but I wanted some info from guys actually running nitrous with a 4k stall. Never hurts to get opinions and learn from what others are doing

 

well, not all 4k stalls are going to be created equal. you can have the same stall rating with a different STR and the converter act completely different. you can get a 4k converter to work well with nitrous, it just depends on your total setup. weight/gears/tire/rpm range/engine tq.... i dont see a problem if your not going over 150 but in the bigger shots most stay under that stall speed unless they plan to turn some serious rpms...

 

I am going next weekend to try a 175 shot with my 4000 PTC 2.4 STR.. I have a good friend that ran a 200 shot on his Ms4/4000 car for many many passes and it didn't blow through his converter.
A loose converter such as Vig I would worry about maybe more than a true 4000 converter.
A 150 or lower and you should be fine.. 175+ is when you should have to start worrying about blowing through it.

But hell, what do I know.. I'm just an idiot.

FWIW, (not that it matters) both of our cars are DD street cars..

 

100 shot thru my 4000 stalled added 80 rwhp. so it may blow thru some, but not enough to matter. do a 150 shot. yes, more will probably blow thru, but will have more hp added. this is just what i think now. i'm not a stall or nitrous expert.

 

Never said you were an idiot man, that was the other guy. We just have a difference of opinions about a certain bolt-on car. No biggie man, I appreciate the info. . lemme know how the 175 shot works with that converter

 

I think it is going to be fine, or at least I hope.. If everything pans out I hope to run some 6.7-6.8s spraying at the end of the 60', but who knows.. If I had tires that could hold a shot out of the hole I would hope for some mid 6's, that will have to wait till next year though.
I will let you know.

 

I feel ya man, I gotta wait for next year to see what my car will really do too. . hell I'm only shooting for 11s with a little 100 shot though. I'm still undecided on which converter to get. .Yank, Circle D, PTC, PI. . I really don't know lol. Pretty sure I'm gonna go with a 4k now though.

 

keep us informed. i have the same converter and a 100 shot. my car still needs tuned after the cam swap so i havent been able to take it to the track yet. really curious as to how it will perform.

 

I will be posting it up in the drag results, and if I remember in here also.

 

I never said anything was wrong with I just said I hadnt seen or heard of it. Im in to see what happens also. Most guys running street strip nitrous setups run 3600s. But it would definately help you for motor runs if you could run a 4000 and still have success spraying.

 

I sprayed 100 on a pt4400 and gained 9mph. Going to try a 125 today.

 

I gained quite a bit spraying 175 thru a SS4K Yank. Only problem was I was on the limiter 50ft before the finish. My limiter is set at 7K so it was def. blowing thru it.
