62/71/13ss vs. 66/71/13ss, why is there a difference in lag

Thanks. I'm gonna need it.

Put some more miles on it today. This turbo really isn't that bad to drive. I wouldn't do it without a cam but with a cam it ain't to bad. I'm dying without this box though. LOL
 
How much slower is spool up vs. the 62? I may be looking at a 66/68/13ss from ED instead of twins
 
Hard to say without the box. Hopefully ill get the box today and I can give you a better idea. I'm thinking around 200rpm. Since you've got a stick and are getting the smaller exhaust wheel I'd say get it. It wouldn't be a problem at all for you to daily drive it. I'm plesantly surprised but like I said, I don't have my box back yet so I can't give a fair comparison.

That 66/68 is probably going to surge. Personally I would do a 64/68. You have to remember that a set of twins are going to spool slower than a single.
Everytime you shift you have to wait for them to spool again.

I know when Weston was convincing me to go with the 68 turbine wheel he didnt like the 66 with the 68.

Besides, IIRC Ron Allen and Brad Ponci say a 64 does better with air than the 66s. I know they both have tried MANY combos.
 
Twins will spool quicker than a big single in my experience. That's the whole reason for going to twins.
 
I believe Tony was getting at the same single in a single configuration will spool quicker than that single used as the secondary in a twin set.

Yeah, thanks Nick.
Been up since 7am YESTERDAY and I'm starting to go delirious.
 
They make these little things called sleeping pills. LOL

Just talked to quadzilla and the turbo timer module on my ADR was burnt and they don't know why. Said it's quite possible it may have damaged some of the tracers to the fueling module so my box may not have been fueling at all. I've run the latest tune on the box (the one that says you have to run to keep it from melting the box) since the day I bought it and I've never used the turbo timer or egt or high idle feature on the box so I don't know why it's burnt up either. Jeremy is going to take a look at it today and get back with me and we'll go from there. Who knows how long ago this thing burnt. The box hasn't given me any problems since I bought it.

Its the 64/68 that doesnt work worth very well a 66/68 works great like the 62/68 but instead of getting the ss housing i would just buy a manifold blanket and turbo sock
 
installin my twins that Chris (ED) is building me right now.... 62/68/13ss over a s475, i am real curious to see how my spool up and streetability is over my 66/71/16 with the fueling. God knows it couldnt be any worse lol

Are you going with the 66/68 kjp i cant remember? Also what are the benefits of a manifold blanket/turbo sock?
 
They hold the heat in and provide better spool up and a little more power. Dyno runs have shown a 10hp peak gain with a 5-10 gain throughout. People have reported 100-150rpm quicker spool as well.
 
BBtank45- you are gonna love how those twins spool I hadthe same setup on my 96 twin turbo truck. I had the stainless exhaust housing though.

66/73/.91 AR T4 nongated
the blanket helps hold heat in and help spooling. After a pull or 1/4 mile run you can hold your hand on the compressor housing to give you a idea how well they work.

If that's been reported about just a manifold blanket I can't wait to see what the new cast stainless diesel 2ed gen manifolds will do for turbo spool and power then put a blanket on it in a twin set with a ss13 ex houseing a setup like that might be dam near o lag
 
Yup. That's the guy. Once my account recovers a little I'm gonna be ordering the turbo and manifold blanket from him.
