CJM stage 2 full fuel return install

O&G

Another win for CJM, been using Charles products for years. His attention to detail and customer service is spot on. 24/7 txt message support and great install pics and instructions. I did the install myself with no issues. Ill attach some pics of the finished product.



I plan to wrap a few areas for heat and debris protection. Other than that nothing left to do on my fuel system until I up injector sizes for E85.

Thanks CJM!

You cant beat the customer service of Charles. He is the man and he really knows what hes doing.

I was just browsing your build thread.

Does the front of the hardpipe clear your turbo OK? I notice you ran the return line down the side of the engine bay where the stock feed line was rather than with the new feed line. Wasnt sure if you were tight on space by the turbo or if it was because it worked out better where you put the regulator?

I ran the return line that way, just because it fit where the regulator was placed and I was able to zip tie it out of the way and away from any heat. I don't think we will have any issues with the turbo as I believe we are doing a custom setup and moving the turbo up to the front bumper where the coolant reservoir once was. I'll know more next week when fabrication starts, but I know JTran kept walking by when I was doing the install saying "That sh*t is badass" lol.

I slipped some 1/2 inch heater hose over the exposed hardpipes as well.

Bottom line is we are all greatly impressed with the kit. Good job sir!

Charles, we endend up sticking with the lowmount setup, we are going to adjust the feed line a bit tomorrow. I'll keep you posted on what we do. I'm sure the BP low mount guys mite have to do something similar. Should be easy though!

Let me know how it goes, I would be curious!

That fuel route made me weary once I saw Johnny stuck with the original turbo location. Interested to see how you adjust for it.

I heard his installation manual is so good a major "brick and mortar" company just HAD to use it too(and give it to its customers)!

Love my stage 2 RFS, more than enough for e85 and is daily driver smooth. Excited your your e85 experience. Highly recommend a fuel starvation product, or keep that beast past half in the tank!

Charles, can I add a larger pump to the road race setup you designed for use with E85 (whatever you recommend)? I read that running E85 does require a decent filter, I'm just not entirely sure where the best placement of the filter should be. I did not receive one on my hardpipes you sent out and I'm sure I'll need to get that as well. I'm going to go this route and just stick with all CJM products instead of running an external surge pump setup from another company.

Power goals on hiboost are above 700whp, I know my pistons are rated to 1000whp, but I don't want to push the K1's too hard as the rods appear to be the weak link in the motor! Maybe I should have spent the extra cash on Carrillo's, lol, but it's too late now!

Thanks,

700 whp can't be that bad on the K1's, seeing all these other guys pushing upper 500 and lower 600whp on a stock block w/ E85. I have all ARP hardware, just not entirely sure how much the K1's can handle. 700whp shouldn't be asking 2 much from their H beam design!

We didn't have to alter the feed pipe. We just adjusted it a bit to clear the boost pipe. The hard pipe isn't near any heat sources, but the flex hose w/ the pre-wrapped heat protection up to the passenger side rail is near some hotside piping. I'll be wrapping it a bit more and of course all the hotside piping will be wrapped as well, but with the amount of air flow down there it shouldn't be much of an issue regardless.

The RRP has 2 pump positions.. one that can hold a standard diameter Walbro or similar shape, and one that can hold the larger 400/485 pumps.

It was designed and has only been tested using a special model 255 in the one position. This special Walbro 255 has a siphon to help the RRP fill itself with fuel from underneath it on the driver side of the tank.

I dont know yet how well it will perform without this special 255 in it. I have been suggesting people to supplement it with a secondary pump in the RRP that is triggered with a Hobbs switch.

However, I am starting to get more and more comfortable with the idea of the RRP not using the special 255 as its primary pump. There is no doubt in my mind that its surge protection will be at least slightly hurt... however with how everyone is telling me they are able to race down to an empty tank... it would seem it has some function to spare and still offer far superior surge protection than stock.

This siphon on the RRP that is built into that Walbro also serves to help transfer fuel back to the passenger side in attempt to extend the OEM fuel sending units pump life. Since we know its always starving badly even if the RRP is protecting the engine from starvation, I wanted it to have a secondary function of trying to protect the OEM pump. By having that siphon active in it, it will increase surge can overflow volume which overflows back to the passenger side.

So anyhow... nobody has tried the RRP without that special Walbro yet.



Just after shipping you your individual S2 fuel systems pieces, I than had to build another kit for a customer. He wanted the 485 in the factory sending unit. This mean cutting out the filter to fit it, which I think is best for a pump that large anyway, especially with E85 since the factory filter is paper and the paper filters are not supposed to be used with E85.

That said, coming up on 3 years my OEM paper filter hasnt given me any problems with my 340 pump.

While building that order, I built it as something I could duplicate as the "S2E Fuel System". The E for external filter. The rear of the 2 hardpipes from the standard S2 is replaced with the external filter setup.

To further enhance output potential, the S2E uses the factory quick connect outlet on the pump as the return inlet, and the added bulkhead is a -6 for the output. This setup bypasses the internal filter whether its been cut out or not. So it doesnt have to only be used with a 485 in the sending unit.

We can upgrade you to an S2E easily. I would make sure that it doesnt cost you any more had you just gone that route (had it existed when your parts shipped).

As for the RRP and S2E... I have already mapped out how to integrate the RRP with the S2 and S2E fuel systems. Having the RRP be a part of it doesnt change anything about the S2 or S2E since the RRP is all in-tank.

The S2E with 485 will do 700+ rwhp, no problem.
