Single Turbo VR4 #2

Great to see you jumping back in!

I never did get a hold of your manifolds... guy got sketchy and stopped replying to me when the deal was about done.

So I acquired an old set of manifolds from Wayne and got my S400 running on mine!

What intake manifold is that? Don't you think its gonna kill your top end?

Nice! got any pictures?

I remember that guy, I sold him the manifolds and crosspipe, he was supposedly going to send them off to some other guy to duplicate the kit. Haven't heard anything since then.

The intake manifold is from a V6 Dodge Avenger. The inlet is almost the same size as a stock 3S intake, but I had to port it a bit. I'm not sure how much it'll flow, but I'm hoping to buy a TIG welder this year so I can make a new one. It'll do for now, I'm just happy to not have to loop the IC piping around to the passenger side.

I don't feel like sleeping yet, so heres some good AEM EMS anti-lag settings for random people that might find this on google:

“alt ignition fixed”
alt spark fixed -8
alt spark trim 0
alt fuel trim 5
alt off over rpm 6700
alt on above rpm 6000
alt off below tps 88
alt on above tps 90
alt overboost 30 (make sure you change this one to suit your setup!)
alt on above load -10

What is it about the exhaust on your VR4 in the first video that makes its sound so amazing?! Is it the 4inch? Almost reminds me of a supra. Looking good so far man. Keep it up. PS, you should find a dyno when you're all done.

Very nice work, looking good!. What`s the spool up like on the single?.

[Roy]

On a 3rd gear pull full boost came on around 4500-5000RPM, theres almost enough time to take a nap while it spools up. Its' really not too bad though, definitely a different feeling than TD04s.

I wasn't nearly done tuning it though, so I'll see if I can improve it this time.

I found this in one of my old threads:

Man Roy, how big of a grin did that monster put on your face every time you put your foot into it?! Everytime I see this thing it makes me want to do it, keep up the awesome work!

Hey Roy, whats the AR on the exhaust on your S400? I can't find something with AR range .80 to 1 from an S400 class turbo. I would hate an AR of 1.32 on a 3.0L.

It's got a 1.10 A/R. I bought it from: Forced Inductions
