Install of a Supercharger or Turbo

[SC2150]

The Top mount Eaton based RX system is nearly finished and we have been running them on the caddy SRX's for several months now. The crank pulley IS keyed on the LLT & LFX.

Your choices from RX are:

Single turbo
Twin turbo
Vortech/Paxton front mount system
Top mount Eaton based.

We have 23 of the RX systems in use around the world with China growing the fastest. Have them in Russia and the UK as well.

So there are lots of choices for you.

Follow my threads and watch the videos.

You also get the tuning suite AND the cable with any RX kit to keep...yours for any logging, code clearing, tune tweaks. No returning it.

Ah ok i see what your saying now. Btw What size turbo's are you using?

They are the smaller Borg Warner EFR 6258 model. Two seem to work really well for this size engine.

what are you HP-TQ ratings on these kits? and what are the RPM's that those #'s were hit at? also whats the pricing on all the kits?

I wonder if you could offset your turbos with a smaller one and then a bigger one? So that the small one will build boost fast and give the big turbo time to spool and build its boost?

Are you talking about one off each exhaust manifold? If so, sure but then you have different back pressures acting on each cylinder bank. Not sure you would want to do that. Borg Warner makes some twin scroll EFRs (small and large wheels in the same unit), but they are long. You would probably be limited to a rear mount setup if you went that route. They are VERY expensive and most people think the single scroll EFRs are too pricy.

Yea those are pretty pricey... haha i just looked them up. But yea that's what i was thinking... and yea the different back pressures wouldn't be too good on the engine.

I'm thinking the different back pressure might impact longevity, but hey so does adding FI to a motor that didn't come from the factory with it.

More importantly would be if it raised issues you might not be able to tune around them.

Idk if it would hurt it anymore than just plain pushing the engine to its limits?

What turbos were u initially using?

Here's my old build thread. Turns out I got the journal bearing model instead of the ball bearing. We restricted them to much and had a failure. Then went to some even bigger ones mean for a twin SS setup until we could get the EFRs. They were very laggy.

Is there a major advantage for going for turbos like the borg warners or will a properly sized set of turbos do?

The technology in the EFRs are just amazing. The have the output of a larger turbo but spool very quickly. It allows you to make power very low in the RPM range and still have carry that all the way up to the top.

Okay, saying someone buys the efrs, would it be easier to replace thr turbos in a kit or build a turbo system from scratch?

Another thing, considering I have an llt and everyone mentions you can only get so much out of it because of fuel issues. Then would it better to go single turbo since youre going to hit that ceiling anyway? And would the efr u use be a good choice for a single turbo setup

Yeah, I think a single would spool up very fast and make plenty of boost for an LLT. Again, they are expensive so if you go single there are cheaper options out there that will make just as much power and spool very well with both exhaust sides dumping into one turbo.
