LS Swapped 408 Billet ETR-HO S484 Toyota Tacoma makes 1050rwhp I have had the opportunity to work with our customer Travis for well over a year and a half now. Helping him with choosing the best parts for his budget and giving him good advice regarding the build of his truck. Travis lives in Jacksonville, Florida which is a good 8 hours drive from our shop. He had an issue with a tuner when this truck had a 370 c.i. motor and busted up a few ring lands because of detonation from unsafe, and quite frankly poor tuning.
To protect his new investment he made in a very nice 408 he had built after the 370 let go, he made the long haul all the way from Jacksonville to Mount Airy, NC for us to tune his truck. Edward Miller of "The Engine Works" built his 408 for him and you may know or recognize Ed's name from his winning Drag Week Plymouth Duster he campaigns. Needless to say, Ed builds one heck of an engine!
When Travis brought us his truck, he didn't have an air filter on the inlet. During the initial tuning session, we noticed at the end of a pull that the boost was dropping badly. Upon inspection we realized a foreign object made its way into the compressor wheel damaging it badly. We told Travis we would give him our cost on a new compressor wheel as it happened on our watch even though we can't really determine what went through the turbo.
Travis took this opportunity to upgrade from his S480 cast wheel unit to the new ETR-HO S484 that everyone has been raving about lately. Unfortunately it was found that Travis turbo was not what he was told it was when he purchased it used. The original owner told him it was a T6, 1.32 housing 96mm unit, but in reality it was a T6, 1.10 housing 83mm unit. So Travis had us upgrade that as well to the 96mm wheel and 1.32 housing that this engine really needs to make the power Travis wanted.
Once we got the turbo back we fabricated a nice little mesh screen that Travis supplied to go over the inlet so no more accidents could happen. We just wrapped up tuning after maxing out a set of 1000cc injectors at well over 80psi fuel pressure.
Quick run down of the engine combo:
Iron block 6.0
4.030" bore
6.125" rod
4.0" stroke
9:1 CR
AFR 230cc cylinder heads
Edelbrock Pro Flo intake
237/241 .640/.630 116lsa camshaft
FTI TH400
Yota rear end
Forced Inductions S484 billet 1.32 housing 96mm turbine wheel
4" downpipe into 4" electric cut-out which is open for these pulls
23psi, 21* timing on C16, B9EFS plug being read after every pull with load:
Remember this is through a TH400(unlocked) and a unknown Yota rear end. From what I've heard these Yota rear ends are not the best when it comes to parasitic losses, but oh well.
Converter is super loose as you can see it stretches it way out. If it were tighter we'd probably see a lot higher torque numbers.
Truck was spinning badly on the rollers, so we had to put some bodies in the bed! Enjoy!

Nice numbers.
Why do I seem to see so many people going with the 400+ ci engines and the S484? I used to read that 1.32 housing and .96 wheel would run out of breath too quickly with it but they seem to run strong and this engine still seems to be pulling strong at almost 7k rpm.

This compressor has a very broad compressor map at higher airflow rates at lower pressure ratios where larger 4" stroke based engines will operate in a street driven application.
Making it a very good match for a street vehicle that operates around or under 7k with 370-408 c.i.
This turbo is a bit too small IMO for anything much larger than a 408, but if someone didn't mind spinning 6000-6500rpm with a 416-427 c.i. IMO it would also work well.

Wow that's killer. The dyno pulls were with the screen on the compressor housing? That is nice if it was because I hear so many people saying you cannot put a screen on because it will restrict it. Are you going to start selling those screens because I have an s484 and would order one today.

I do think it would be a little more efficient, as the sweet spot for this turbo seems to be 375"-400" engines.

It really isnt a mesh screen that most ppl rig up, the holes are larger and it seems like it would have no restriction at all. Still yet it will keep out those small pebbles that are always on the roads that your tires like to kick up.
