Re: Ripp installed.

Exactly, it's pretty much always the tune, or lack of. I'm running 8.5 PSI (almost 9 PSI when temps are in the sub zero's) but have no issues after a few thousand miles of hammering. I'm running 580 RWHP (dialed way down).

So, the major differences I have seen in the Jeep world, is that many who install blowers use a canned tune, or a tune and datalogger for remote tuning.

In most other cases I see with performance tuning, I see guys putting their cars on Dyno's during the build and tuning, with very extensive tuning taking place. That's something I don't believe you can achieve to the same degree of precision with just datalogging and remote tuning. I also notice that many of these blown engines are using tunes by the same "tuners".

The guys I use for tuning have a lot of experience building and tuning SRT's of both generations. The tuner there had explained what the issues are in the 6.4's and what to avoid during tuning, which is timing. When we tuned, on the Dyno and in the streets, he left a lot of timing and leaning out of the tune, to run much safer. So, I'm not fully optimized on AFR or timing, and we figure there's about 50-70 HP left in there, if I want to go ahead and forge internals, namely pistons.

Eventually, I'll do that and unleash the rest of what's there at 8.5 PSI.

That said, the Centri blower should still be kicking ass, but at 5 PSI, it won't blow your socks off. If you have a good local tuner who knows these builds, get a smaller pulley and belt and let them tune at @ 8.5 PSI. That will make a huge difference.

I run one of my cars with 18.5 PSI on a Vortech YSI blower, making 1050 RWHP and it belts out a hell of a lot of power. I can't even put it down because I never built the drivetrain, so I'm running Nitto's that just spin at part throttle in any gear at any speed. LOL

Your issue isn't the BOV or the blower; it's the tune and low boost you're making, that's all. Get a good tuner who's done these trucks and let them make the changes you need. You'll never look back.

@ Fairbird...either one will net you pretty much the same overall power and speed in this case. RIPP isn't Whipple. The two are just very different in the way they deliver the power. But if each were to optimally tune @ 8.5 PSI, you'd probably see pretty much the same power from each. One makes more TQ at low speed and the other makes it high speed. One uses a BOV, the other doesn't. One looks factory installed, the other doesn't. Etc..etc....etc....

RIPP doesn't build a thing...they just assemble kits and maybe bend some tubing. Vortech blowers are available to anyone. They use the Vortech V3 SI trim blower, good for about 700 RWHP in a solid build. All RIPP does is either fabricate the bracket, or have it done by a machine shop and they ONLY do a few Dodge / Jeep vehicles, nothing else. They are a small garage style kit builder. They don't build the blower, the BOV, the intercooler, the pulleys, etc...

Most of the blown 6.4's I've heard about are equipped with RIPP kits and RIPP base tunes....

Whipple is a whole other story...

YMMV

Re: Ripp installed.

I agree it's all tuning , but my buddies whipple slower on low speeds too lol . Well I'm not running can tune I went thru 25 -30 revisions , since I have 5000 on the kit and 9000 on the truck , runs good , idk how much power but 3.4 all the time and below 12 sec 1/4 mile constantly . All that makes me think that Ripp is a good kit .
Ps my other car I'm running 37 psi and can put the power to the ground , cheers

Re: Ripp installed.

Vortech blowers make good solid power. I'm guessing your other car is a Turbo Diesel truck?

Re: Ripp installed.

Throw some Pistons in and turn up the boost

I don't know if I want to throw that much more money into it. If I did pistons, I'd do rods. And if the engine is dropped I'd put headers in while its out. Adds up to $4500 real quick

Re: Ripp installed.

Anything else needed besides pistons and rods to make it safe, in your opinion?

Give it a little learning time. Took mine to the track last night with the Ripp supercharger setup and went 11.876. Only performance mod done other than Mufflex muffler delete.

Wow, thats great times. I just got forged pistons/rods so after they are installed I'm shooting for around 700hp.

If you don't mind me asking what are you looking at cost wise for parts and labor for forged upgrade. My truck dynoed at 567awd hp at Ripps facility. He told me that was with a conservative tune and roughly 6-7lb boost. I know there's at least another 75hp or more there but don't wanna break anything so forged would be a must before tapping into it.
