big-daddy:
i should be getting the new VA tomorrow. are you going back to proven performance this weeekend? the line was so long last ssunday i couldn't hang around. CHAZ607 and i are goinging to try to get on the dyno this weeekend..... james

The plan is VA and exhaust in the AM and Pruven in the afternoon. I won't know for sure untill Friday. I will e-mail you.

i don't know if it has been tried , but i would think that the VA and the EZ together would be a bad idea , they both increase timing and to much will not be good .

as far as new VS old i believe they either delayed fueling or cut it back , an old VA and 275's would smoke a bit at lo boost , this along with no boost module has been my biggest complaint of the VA . add a PE on hot #3 and it will smoke , though not real bad, the whole time your foot is in it .

Assuming dealer service and price are about the same between the VA and EZ, if you test them out on a dyno at the same time, minimizing "seat of the pants" variables, there's no doubt which box the VAST majority of people will choose. Edge has done incredable R&D on their products.

Because of the waist gate, the boost will still stop at around 19. There are thousands of VA users out there who don't run boost modules. Probably don't need it until you add injectors for even more fuel.

Pete, you shoulda hung onto your old vA. It was an old vA I tried out a few weeks ago.

From what I've heard about the new vA, it is tamed down, and compared to the EZ, the EZ is the one to go for.

Here's a picture of my dyno run. Mods are scotty air,4" exhaust,EZ box,and hx40 turbo. The first run is with stock fueling+boost module and the second run is with the EZ plugged in. The torque numbers at 70 mph(1960rpm) are 423 stock 683 EZ. http://albums.photopoint.com/j/View?u=1506659&a=11375901&p=43474372&Sequence=0&res=high

I've had my VA (old model) since 9/2000 and have been extremely happy with the performance. Very smooth right off the bottom. 19-20 lbs max boost, as should be. Just added the PS boost module/elbow today. Solid 29 lbs boost and seamless throughout rpm range. I've had real limited exposure to EZ so can only comment on VA.

What exactly does a boost module/elbow do. Who makes them and where can they be bought. I have friend with a VA and he wants one but is also new to bombing.

boost module and elbow are used to fool the ECM into seeing less than 20psi boost and not defuel , the module connects between the map sensor and the wiring harness , the elbow replaces the brass elbow on the turbo to the wastegate actuator to keep it from opening and dumping boost . Practial Solutions sells a stand alone unit as does DD .

when pulling off the hose clamp on the elbow be very careful , grasp it with a pair of pliers and wiggle it and the hose off the elbow , remove the clamp and store it in a safe place , when you go in for work at the dealer you want to swap it and the factory elbow back on as a nosey dealer that wants to wiggle out of warranty work will look for that elbow and clamp with the green paint daub ...

if you have an 01 auto it has a hardlined wastegate and the elbow is on no use , there are other ways to defeat the hardline .

I thought the new VA gives slightly more grunt than the old version. Anyway, I have the new one now, after returning the old one which was working only intermittently. Customer service is absolutely A-1. The newer VA is better sealed from the elements, and as usual, power delivery is smooth and seamless. I also have 275's plus the PE. This is a great configuration as it allows for several different power settings. Even with the Edge off, the boost module allows for 35 psi with the injectors and VA. If I was in the market, I would consider the new Edge Comp which combines timing advance plus fueling.

THANKS MOPAR MUSCLE!!

It is the information and time people like you provide, that makes this site what it is.
Much appreciated!!

What are the reasons for the stock set up to limit boost at 20psi? Emission control, fuel pump life, or what? What are the risk to adding the boost module and elbow?

Would you gain any performance by only adding the boost module and elbow to a otherwise stock set up?

[Max Wedge]

I don't have either "box" yet ($$$$), but to answer your question, I beleive the boost eldow alone will cause your "check engine" light to come on, and leave an over boost code in the ECM--thus negating your warranty--possibly??? The boost elbow is designed to work in conjunction with a "box" that will limit the voltage the ECM sees for boost preasure. Factory ECM seems to de-fuel if boost goes over 20 psi. so I doubt that the boost elbow alone will have any benefit on a totally stock set up.

TowPro, there is only one old vA. When Bob Wagner let several of us try his old vA at a NW BOMBer event recently it got passed around between ETHs, ETC manuals and ETC autos. It worked great on all of them.

With just the VA on my '01 ETC 5 speed we saw 240 HP on the ground using a Sun dyno just last evening. I get 20 lbs. boost, and 1250 degrees max preturbo under sustained load. I only see 1250 degrees at higher rpms - 2500+. I'm going to place my order for boost module tonight, will let you know results after our NE Iowa dyno days. Ray

All this talk about the New VA and the Old VA has me confused?

Here is how I thought it worked.

The old one has a case with fins on the top. It was designed for the 98-2001 ETC engines (standard HP levels)

The new one has a case with no fins on the top.

The programming was the same for both the Old and New VA, except they introduced a model that worked better on the HO Cummins, and it is only avalable in the new case.

So now there is 2 modal VA's The 98-2001 standard HP version for the ETC Motors, and the version for the ETH motor. (both in the same new style case)

Am I wrong?

 

[ramfan2]

Any opinions on which one would perform better towing?

Also, which one is more likely to smoke.

Thanks again!

Chris,

I think you, John and I all met at the end of the Timberline Rally last summer... . shoot me an email if you want to hook up, that way you can test drive a rig with a VA on it.

If you are familiar with say, Cabbage Hill, Govt Camp, and grades such as those, then how's 60 mph UP Cabbage with a 6k travel trailer grab you?

Just an opinion here but if it was an auto transmission I would want the power to come on a little later in the RPM's to give the transmission time for more fluid pressure and coupleing. Just something to think about with the differences between an auto and stick.

P. S. Soon there will be another product on the market that I feel will be superior over all the boxes. IMO you just can not get any better then a modified ECM, HINT #ad
(MARCO). I just hope they keep the price with-in what us lower budget people can afford.
