If you are looking at possibly over 700hp, I would only take the advise you get on here so far. Not that there aren't a lot of knowledgable people on here, but they aren't the experts. Only each company is going to know what flow numbers they are getting out of their pumps - a stage 2 from Floor It and a stage 2 from II are not likely going to flow the same numbers. I would be calling the different shops and talk to them about where you are headed with your truck and they should be able to tell you which choice from THEIR selections will meet your needs.

 

thanx 4 all the advice and i will prolly be goin with the dual cp3 kit because of the warranty and also i wont have 2 worry about low fuel rail pressure.....but thanx again

 

The ATS kit has my name all over it...Lol! I like how they tie into the rail and the kit looks much better than the relentless kit. I like the billet wheel and I dont think I would like the green belt. JMO. Plus I like how ATS ties into the rail compared to PPE.

Ive talked to a few that are running their kit and they said they had no issues at all with the installation. So thats a plus.

 

Make sure you do your home work. Take the time to make phone calls and talk to people that are running mod cp3 and twin cp3. Be true to your self and were you are going to go with the truck. John at floor it has my vote his pump rocks.

 

Luken,the Relentless kit comes with a black belt,mine is green because it was the only one I could find when the prototype was built.If you would do your homework the ats kit is a terrible setup.Yes they feed the rail in two spots,but they relocate the rail sensor to the cp3.Do you think you can get a accurate rail pressure reading at the pump,I dont think so.The sensor has to be at the rail so the ecm knows when the rail looses pressure,the pump will never loose pressure where ats locates the sensor.The ats kit does have a nice pulley,the relentless kit was built with affordability in mind.The ats setup also uses a radiator hose that looks like a total hack job also.

 

Heck...John ALMOST warranty's work done by "other" CP3 modifiers.

 

John has my vote too!!

 

RC, Are you saying the ATS kit is junk? The last time I checked the fastest truck on fuel was running their pumps...

So how much difference in pressure do you think there is between the feed lines from the cp3 and the rail?

 

who is that? just wondering

 

Member greyrig05...

I never said any of the kits where bad. I just simply said my opinion. The only picture I could find on relentless's website had a green belt so I assumed they where all like that. I'm sure the kit works as well as the rest of them.

 

Not to say anything bad about anybodys stuff, I think that this winter I am going to put a relentless dual on my truck, but Mike Drevers truck is running a single cp3 from IIS. And he is right there with greyrig on #2 and now officially in the 10's with n2o. But he is planning,, if not allready done, going to a dual pump setup. I am putting a IIS pump on my truck to get me through the summer,, then next winter look out

Guys you got it all wrong, daul stage 3 pumps are the way to go

 

I dont think they offer them yet Rat

 

is relentlessdiesel's 10 second cr fuel only or not???? not rc's but the 2wd truck....i dont remember reading anywhere he was spraying



i think he may be running the relentless kit.....lol

 

he's running my FCA in one of those pumps too!
