The Sean Roe Supercharger *****...

[SUN RA KAT]

...Air Through The Throttle Bodies. And some people have their Sean Roe Supercharger already installed but they haven't posted a report here yet!!!

I'm #35 on the waiting list and am impatiently waiting for my ship (from Sweeden) to come in. I talked with Becky today and my supercharger should be coming on the ship from Sweeden the week of October 21st.

I want to read what the supercharger is like until I get mine and post my report here. So those with your Sean Roe Superchargers installed <FONT size="4">POST YOUR REPORTS!</FONT s>

Thanks.

WE NEED DETAILS!

Reality:
My Viper is the first "stock" (unopened motor - only mods are tubes, filter and HF Cats) Viper to receive the Roe SC. It has required some tweaking to get it perfect. The time necessary to tweak and road test, due to bad weather, has caused some delay. At the moment, I can only report that the Wiz was heard speaking of a "***** ape" after one initial test drive. <FONT size="1">Do you really think I could keep my mouth shut if the install was completed?

Kenny, Sean is way too nice a guy to go scaring him like that.

Rather like the "Doug Levin I'll see you in Court" . . . "for attempted ******" thread one of his customers recently posted. I hope Sean rolls you over into the next batch.

Hey CitySnake,
I think that was your Sean Roe Supercharge I saw delivered via FEDEX to the Wiz's place when I was getting my car serviced.

It was sitting just 2 feet away from me in the lobby area.

I wan't to open that bad boy and check it out. So did the Wiz, but when the Wiz called you, you told him you wanted to be there to open it yourself.

daamn IT!

I wanted to see it.

Ohhhhh the jealousy...

Well, at least I saw the box before you did. SO THERE!

I considered grabbing the box and making a run for it. But then I'd have to find a new Viper tech to install it. That and the box weighed bout 90lbs.

&lt;sigh&gt;

Sincerely yours,
Still Green with Envy.

RedGTS - Sean is like way cool to make sure everything is right on his supercharger before he released them even if it's taking several months longer than first projected. I figured the people who have their superchargers installed would have to read my controversial topic and then post their own experiences. Yes, I have a roll of paper towels by my computer to wipe up my drool for when the first person reports start coming in. I promise to post my report as soon as I get mine installed.

Hi Guys,
Yes, I know the supercharger ***** (air), but did you know that it can **** water (and alcohol) too....(dyno testing Saturday).
Right now, there are 5 production kits out there, most of which were recently installed (within the last 1-2 weeks). One in FL (our '96 test GTS), a '97 in Texas (SW), a '97 in CA, a 2001 in NY and a '96 or '97 in the UK. Mechanically, everything is going 100% well, as in everything fit up properly, no vacuum leaks, etc..
Of the 5 cars, you've heard our results and heard / seen SW's. The other 3 cars are running fine, but are requiring some adjustments and the owners are not hammering on the cars until we get them taken care of (nobody wants to see any engine damage). At full throttle, 2,000 RPM to 3,000 RPM, they're getting some ping, but it goes away once the RPM goes up (high cylinder pressure and low piston speed with just a bit too much spark advance for the fuel octane at low RPM). We ordered in some MSD boost retard boxes for these cars and water injection is an option too. This will not be difficult to overcome, but is requiring an extra week or so of patience on the part of these owners (which we appreciate with these introductory kits). Once we get these cars tuned in, the owners can hammer on them.
That's the straight skinny on what's going on right now. Other than that, we have a lot of parts out at powder coating and we have the final shipment of Superchargers on the way to complete the first run. We'll be talking with each customer about his / her kit and what we're seeing on this introductory run when we contact them about shipping. Most kits will be going out next week.

Sean,

Do you offer the Burgundy/Silver paint option as a Kit?

Congrats on the SC Kits!

<HR></BLOCKQUOTE> Hey Sean,
So would using a couple of cans of octane booster or a higher octane fuel (100) be better than retarding the timing? You know to get more power? Yep, still looking for the Gen I,

octane booster is a scam.. its claims to raise the octane by one or more points, but in the octane world 1 point equals .1 .. for example boosting 91 octane 1 point does not make it 92 octane, but rather 91.1 ...

i'm sure 100 octane fuel will solve the problem, but who wants to run race gas all the time? even running a mixture would eventually become cumbersome..

just a little ping is no big deal and i'm sure it will be worked out..

this is probably more of an issue for the cars that are unfortuantely stranded in 91 octane states such as california..

I believe you got it right

No need to be jealous...buy one yourself!

Funny that Sean didn't mention his new Viper loaner program in this thread. Guess it's only for the first group of 5.
Must....hold ....on....just....a....little....longer....

Can the VEC1 handle the pinging issue?

Just move to Texas where you can get 93oct gas!! I have not had any pinging on pump gas(93). Drivability is great& instant boost. I didn't have the VEC installed before the VOI, but now I do and the car drives much better and smoother. I also found out that a couple of valves were adjusted a little too tight. My car ran consistant 10.70s@130-131 at Bowling Green. I think it's faster now.

I will be going to the track soon for some better #s..

I use 93 octane gas here in Ohio, but could switch to Sunoco, where 94 octane is available. Ohio may have too many motorists on the roads, but at least we got decent gasoline.

 

[varanus]

Sean, will I be getting one of those MSD boxes sent to me or will that be an extra item? Ted and i will be working on the car this weekend.
I agree with the water alcohol injection and as soon as the kit was announced I was already planning on it. With the system i am getting it reduces inlet air temp 65 degrees so it will help a lot.
I was talking with an LS1 guy tonight and we were talking about pinging with roll acceleration at lower rpm. He gets it too on his car and it is NA. He said he thought that the low intake speed wasn't getting the richer air fuel mixture to the engine quick enough. I also saw a post about some of the older saleen mustangs having the same problem. They had to retard timing a little at that instance.
BTW at a recent Mustang car show the viper's sc got a lot of attention!

 

[jimandela]

SUN RA KAT,
On my stock engine I only run Sunoco 94
And my car runs great.
I would recommend this "upgrade"

Also, newest yellow mod.... I painted a toy rubber snake...
Yellow. I looks sweet on the dash.
Look another thread yellowjacked

jimandela - My car runs great on BP (British Petroleum) 93 octane. Also my Dodge Ram (required with my mods).

<HR></BLOCKQUOTE> Pinging is the motor wanting to run backwards from detonation. Forget the water injectors there not fail safe. The MSD box is the best way to get rid of pinging.

[ronviper]

Sean Roe so far i have only seen test on older Gen2 cars what about your system on 2000 and newer is that going to be a problem with the pistons.

 

[toddt]

It's been my experience that the only way an MSD will eliminate pinging is if it has a boost retard.

High energy sparks help spark blowout, not pinging. If I'm wrong on this, someone please chime in...

FYI all of you!

Boost Timing Master, V10 Dodge
 If you’re one of the lucky owners of a new Dodge Viper or a Dodge V-10 equipped Ram truck, and install an aftermarket supercharger to the 10-cylinder engine, you will need this Boost Timing Master. With the increased cylinder pressures that the blower produces comes an increased chance for detonation. The BTM allows you to retard the ignition timing as boost pressure increases. Once there is two pounds of boost, the BTM will begin to retard the ignition timing according to what you program with the adjustable potentiometer. You can set the amount of retard that is removed per each pound of boost. A total of 9° of timing can be removed.

PS. I already have mine on the way! Snooze you lose!

If you retard timing, you will loose considerable HP........ But it's better than detonation...... Good Luck and just wait until you BOOST!

Gerald

 

[RedGTS]

Steve, you're always leading the pack on everything!

Questions for Sean or others:

1) I'm assuming this is the boost retard unit Sean was referring to. Should everyone go ahead and get one, or should we approach it on a case by case basis?

2) How much hp will retarding the timing cost us?

3) If the pinging is only at low rpm WOT, can this unit be adjusted to pull timing at low rpm and put it back at high rpm, or is it strictly boost driven? I'm assuming the answer is the latter.

4) Is the water injection likely to reduce or eliminate the pinging on those cars that have it?

 

[Bugeater]

Like RC Viper, I too want to know of any experiences with the S/C and Road Racing. PLEASE respond when there is anyone that has gone to a 2 or 3 day event with at least 4 hours of track time!

 

[David]

Keep in mind that detonation does not always produce audible pinging. It's possible for your engine to be detonating any time you notice a slight "dead spot" in the gas pedal when accelerating... I had a Saturn SL-2 turbocharged years back and I had to watch it's plugs like a hawk and inspect the pistons for pits. I used forged JE pistons -- and with that combo I almost never heard a ping. But, detonation was definitely occurring during low RPM and high boost. I couldn't find a boost retard unit usable in a Saturn at the time, so I used water alcohol injection. It worked, but cylinder #1 always ran hotter -- despite testing the water mist flow in a duplicate induction tube made from transparent acrylic. I attributed this to the bizarre Saturn fuel injection and not the water injection. The 4 cylinder Saturns fire all four fuel injectors at the same time (not sequential) -- so some unevenness in the mixture was probably unavoidable.

If I had a choice between a purpose made boost retard unit for a Viper or water injection, I'd choose the boost retard. Constantly filling the water tank and dealing with a gummy throttle body was a hassle on the old Saturn. As long as the ignition timing isn't ******** too much, the exhaust temps shouldn't rise too high. Of course, checking 10 spark plugs for signs of detonation is a lot more work than checking 4!!!

You could always completely control your entire system using a motec.

But then you would not have any problems left to try to fix.

We only have TIME. How much is yours worth in chasing these types of issues?

[RedGTS]

So how much for the motec, Jr.?

i didnt mean that the pinging wasnt bad for the engine, what i meant was that its "no big deal" since the issue will be solved..
