Removing the ROE setup on my car

[BK99GTS]

I am late to the thread, but I have a new generation ROE kit and have been very pleased. They spent a ton of time on the intake which was the biggest issue with the original versions. The supercharger dumped straight into to the plenum and resulting in different fueling needs for each cylinder. This is what required the tag-along management system which as I understand was difficult to tune a bit temperamental. Their current generation system provides individual runners to each cylinder that have been flow matched to ensure consistent fueling. As a result, the factory ECM is can handle everything and tunes can be loaded with an SCT hand held. As far as WM injection, it's all about boost level. For the '01, I am guessing that you wouldn't be running more than 5 or 6 psi of boost which wouldn't necessarily require WM. That said there is a definite benefit in terms of safety. Unless you are just wanting to extract the cash for something else, I would highly recommend talking to ROE about upgrading to the current generation intake and get it tuned. Just my $.02

Thanks for your feedback BK99GTS! I have thought about just keeping the ROE on there but I haven't looked into the 'updated intake' you speak of. Are you talking about the intake tubes or the intake manifold under the blower?

[dave6666]

I've been running 8# of boost in my creampuff '01 for 8 years. Dan Lesser has scolded all the tuners that can't tune that without blowing it up.

He's talking about the intake manifold not the intake tubes.

Cool! I figured so but wasn't sure. I'm going to speak with ROE again and see what an updated intake manifold will cost me.

[Charged01ACR]

Well looks like ROE has an updated manifold kit just for my outdated VEC setup.

Very tempting

[BK99GTS]

Worth a try and is an incremental cost vs a complete do over. I think you would be able to get most of your money out of it if you wanted to take it off and sell it down the line. Agree with Dave above regarding the necessity of WM for a modest boost level. You already have it though, so a sunk cost. The equivalent of taking off a mechanical intercooler that was already installed. You could do it, but why? You might also want to give Justin at JMB a call for his cold air intake setup. It does a great job of leveraging the NACA and lower air dam as a true cold air system if you get the extended version. He also welds bungs in for WM injectors if you are going to keep using it. See the link.

Well the teardown has commenced! Should be back on her feet by the weekend

I've seen pics of the "improved" manifold design. Still missed the issue since it wasn't an issue of needing individual runners to even out air starvation under vacuum in the old design. Its ALWAYS been about available air volume in the plenum during vacuum/cruise. All this new design does is take the available air volume under vacuum and squeeze it into 8 small runners, relying on the blower to compensate for the fact that there isn't a volumetrically sized plenum for each cylinder to draw from. My modification was the ONLY solution (right-sizing plenum volumetric efficiencies) to that issue. The original manifold design just needed more VOLUME, not runners that actually decrease manifold volume. You have to remember that under boost, ALL AIRFLOW ISSUES go away regardless of manifold design. All cylinders are physically equalized under boost and the best way to ensure that happens is NOT with individual runners machined into the manifold but to allow air to reach the intake runner from an open plenum. Look at the Hellcat plenum, the Mustang plenum, the Corvette plenum, and so forth. None use individual runners and ALL have an open plenum designs. This "new" design was meant to ONLY address the issue with the rear cylinders being starved from inadequate airflow during vacuum (due to too small of manifold volume for an 8.0 ltr engine). It does absolutely nothing to improve airflow under boost; the older design did quite well. So funny to read all the misperceptions on what this manifold tries to fix.

[BK99GTS]

Not sure what your modification was to resolve inatake volume but it would appear that you agree there was fueling problem with the original system. As far as misperceptions, not sure what you are referring to that is relevant to this conversation. The new intake addresses the issue (perhaps not to your liking) and allows for tuning with the factory ECM. These were the issues that the OP was discussing to begin with. Also think ROE spent more time on the new intake flow testing with VE in mind than you are giving them credit. That said, this is just one guy's opinion. I own and have experience with the new system, but my only experience with the previous generation was though affiliates that described the tuning/operation with the VEC as temperamental.

I didn't say he was an idiot, just his premise was idiotic........... And it is.

Your premise is idiotic, and incomplete.

W/M as used in this market is a JOKE. I have seen countless engines with internal corrosion issues due to W/M. I have seen countless engines that end up with issues because someone used W/M as the intercooling method during tuning, and then when the W/M system fails, the entire platform detonates itself to pieces. As the ambient conditions change, W/M drastically alters the required fueling, more than the OE controller was ever designed to accommodate. The Viper market has turned a "safety system" into a fucking crutch of intercooling, and it makes me sick. W/M creates FAR more problems than it solves in normal circumstances as seen in *THIS* market.

I prefer to properly build the setup, and tune without W/M. If you then want to roll the dice and add W/M on top to create a safety margin and drop IAT's, then have at it. I see no issue there, provided you use a QUALITY SYSTEM that actually has injectors and mapping, not the happy-horse-shit that everyone in the Viper market uses. At least if the more-than-likely piece of junk system fails, the engine is still within its original safe tuning strategy. The entire idea behind W/M has been perverted, and the control systems utilized are just as big of a joke. If the system does not use a high pressure pump, timed injectors, have full mapping, and fault finding/flow monitoring/bottle level warning, it has no place in a properly built engine bay... certainly nothing I will build.

Next time you try to equivocate my name with an "idiotic premise", you should probably just accept the fact that you don't have all the facts up front, and resist the urge to say something stupid.

Enjoy your rust bucket.

There were so many more problems with that example and you're putting it all on water/meth. Nice

I have over 20K miles on my Roe and it look nothing like that. In fact the heads looked perfect, the cyl looked perfect. If it is done right, there is no issues. If you are using it to make max power, yes it can be detrimental if the pump fails, but the Roe develops so much heat that after it gets warmed up and starts getting hot, the tune is not accurate enough to change for the heat increase which is why you have not been able to tune a Roe properly.

With the use of water/meth, it keeps it relatively stable because it does cool efficiently and the tune is more stable. Will you run into issues if the pump fails, absolutely. That is why you should monitor the levels and pressure under boost(when it should only be pushing fluid) just like you monitor your oil pressure. Will your engine hit detonation if the W/M pump fail? Yes if your are on the ragged edge, but if tuned conservatively, no and you be able to monitor if there is an issue. that rotor was sucking so much blow-by the engine was in need of a rebuild before the roe was installed.

NEXT!!!

My modification was the ONLY solution (right-sizing plenum volumetric efficiencies) to that issue.

I know you've moved on to your own manifold design now, but one of the 4 that had the plenum mod - mine - is now off the car and close to entering the free market. And to think, Mike's new friend Dan Lesser tuned it.

NEXT!!!

Pick me!



I love car forums.

I would be interested in it when it does, please PM me.

Do you mind taking a picture of the back of the intake Y and inside the SC? I am guessing yours looks as clean as mine did..................... For the new buyer...................

A couple of examples versus the guy who builds the engines for a living. Now that's a great sample pool!

Keep it up Mike. Apparently you CAN argue with common sense, physics, and chemistry.

It doesn't take a rocket scientist to figure out what happens when you have water and methanol, both of which are corrosive, in the presence of materials........ which are prone to corrosion. Especially if you have a nozzle issue, a vacuum condition [dirty filters], colt climates, or any other number of things that would contribute to the mixture sitting around in the manifold.

Hell, given how many W/M pump and driver failures I have seen... it wouldn't surprise me if your meth tank is actually evaporating rather than going into the engine... it would sure explain the cleanliness you claim to see!
