98 4.0 SOHC with STS turbo and Bamachips tuning...
Hey guys,
I've got a local customer who's just completed his new STS turbo system on his Explorer. It was a completely custom kit, everything was made custom except for the turbo. He came over tonight and where as I don't have the time just yet to goto a full dyno tune with him we got it running safe and with a great power. We'll be going to the dyno very soon.
After a test drive with him on the 2-3 lbs we got everything set and running right. It pulled good, more so like a mild V8 without any punchy power band. It was nice but we wanted more.
Next he went to the back and adjusted his wastegate controller and raised the boost to 6-7lbs and WOW! This thing flat out HAULS BUTT! I just kept saying " Wow, all of this in an Explorer too" hhahaa.
I kept putting the tuning to it until we finally had to stop, we were starting to get knock sensor activation of just a few degree's, 1-2 degree's. I backed it down a few and told him that'll we do the rest of the tuning on the dyno where we can ensure a proper a/f ratio. We've already been one time when he was n/a and tuned the Explorer for use with his 76mm C&L meter.
His list of mods include...
Custom STS turbo put together by www.GraceMotorsports.com in B'ham
76mm C&L meter
30lbs injectors from Explorer Express
Bamachips X-calibrator Tuner
I'm not exactly sure what size the turbo is, I think he said something like 63/58 ?? I don't care what size it is, just how much airflow it makes.
He doesn't have any pics of the way it routes so for now I'll tell you. The turbo sits where the spare tire was, then the piping comes foward along with passenger's side and then up above the tire and through the wheelwell to the MAF and then the TB. He used the MAF in a blow-through design and made sure it had plenty of straight piping both in front and behind it.
Here's some photo's to tease you with :)
STS Turbo #1
STS Turbo #2
STS Turbo #3
STS Turbo #4
STS Turbo #5
STS Turbo #6
This should get real interesting as he also has a Snow Performance boost cooler and we plan on making a 93 race tune for the track using 10psi and the water injection on the dyno.
Later Doug904.

Does it have a crap load of lag from being mounted that far back. I know I had a t3/t4 .63 exhaust and 60-1 compressor on my cavalier before I sold it and I didnt get full boost until about 4k and that was right by the exhaust going through a header. It was alot of turbo lag compared to some guys that I new.

No, not really a large lag time because you always have the air flowing through it. You don't feel the full effect like a M112 on a 4.0 but when you hit about 2500-3000 it just flat out hauls butt. Also, those are preinstallation pics, he has a filter sock or Outwearer I think they call it. According to the STS website it's fine but the only thing they don't recommend is totally submerging it in water.
Dyno numbers soon to follow!
Thanks, Doug.

I couldnt have a turbo under the car/truck it HAS to be up there with the engine. It's just my opinion, I like to look at Engines then see theres a turbo tucked around the engine running 8-15 lbs boost. With an intercooler attached for looks and function. I dont know about everyone else but if i seen an edge with an intercooler behind the valence I would faint. I would be way to worried with a turbo near the gas tank, near water (puddles splashing up), rocks, dirt, mud, snow, sand. I would feel safer with the **** up near the engine.
