I have a 369 .91 t4 showing up tomorrow to start messing around with. Will be replacing a gtx40r.

The best pull was 537.4 HP and 1081 TQ uncorrected here at 5700'. The customer did not have gauges and it was late when we got everything buttoned up and on the dyno so we didn't even rig up a temporary EGT gauge or boost gauge.
Do you have rpm for those numbers?

That 2006 Common Rail made peak power around 3100 rpm as I recall.

Here's the hour long video feed with split screen showing the dyno, lots of free info if you can handle the long unedited feed....

here's my setup:

borg warner sx-e 64.5/73/.9 T4
steed speed
22* timing
fass 220 gph (55 psi at wot)
power driven 7mm dv's
infinite perf 5x.16's 155*
4k gsk
afc live race (I see 50 lbs boost)


I don't know what power I am making, but I have to tell ya.....it doesn't seem that fast. The motor is a 96 ppump 12v but its in a 92 rclb 1st gen (which only weighs 5400 lbs). I know I have 33's that are 14" wide, but I always hear people saying they can spin the tires at 40 mph etc and my truck barely seems like its throwin me back in my seat. I went with the 64.5 to make it a driveable truck, but I'm almost thinkin I should have went with the 69. I guess I should be happy at my power level because even though my old second gen felt faster with the 66mm and 5x.18's, it was a pain to drive and keep everything in check. Maybe I just need a second turbo haha. Egt's at wot are 13-1400, and when I get on it, it'll smoke a bit and then lite the charger and it whips right up to 45 lbs boost so everything seems like its working properly. If I'm at 500 hp, it doesn't feel like it. Other than that, I do like the charger for what it is.

Boost leaks? What cac? Might bump timing also.

bhaf into charger with v band elbow into stock intercooler pipes, 2nd gen style intercooler, stock intake horn. all PDR boots. New intake gaskets etc so there shouldn't be any boost leaks and I am seeing 50 psi. I had a s400 64/87/.9 on there before, full cut dv's, and 18* timing, and it felt faster than now, but the egt's were insane. I don't know....maybe it is fast for a truck and it just doesn't feel like it?

Cooler can still be leaking. Well worth the check.

I just might do that. I wonder how much these chargers can be pushed. Being non wastegated, I figured 50 was a safe number so as to not overspin the s300.

The second half of the video is a couple dyno runs with a new 362 SXE machined for 2nd gen discharge elbow, and fitted up with a .70 AR wastegated T3 housing. This 98' 12v did just over 500 HP and 1100 FT LBS uncorrected on our Mustang Dyno at 5700' elevation. The relatively flat HP curve closely matches other dyno results we've seen on trucks/turbo setups that are "fuel-limited" not air-limited.

Fueling setup is a factory 180HP pump with 24* timing, PDD 5x014" 155* sac injectors, 024 DV's, 4k GSK, PDD Stage 1 lift pump, AFC LIVE Tuning.

Fuel limited? So are you saying that is not a optimized combination of parts? I was looking at the same turbo and .70 housing for my 160 pump swapped D250. 155* injectors? Swapped out his pistons or spraying out the bowl?

By Fuel Limited, I'm implying it's not "out of air", the turbo could support more HP with more/better fueling. This is a street truck, daily driver, tow beast, so the owner wouldn't be best served if we bumped the timing up farther or went with larger injectors. It's an honest 500 rwhp truck that spools well, tows well, gets excellent fuel mileage, and is tuned to run clean. It's a great combination for a street driven 12v single turbo setup.

As far as piston bowls, this is a fresh engine build with new wider bowl pistons, it's definitely spraying "in the bowl".

I reread my post. It was poorly worded and frankly not all that useful. I guess I was just surprised that a 180 pump at ~24* with 5x14 was maxed at 500hp worth of fuel. Im curious if the AFC live was tuned for max power or some kind of EGT/smoke compromise.

BTW I'm seriously looking at getting this turbo from you guys. Hence why I ask so many questions. It does look like it hits a sweet spot on these trucks. Anything more and I'll need billet input/output shafts on the trans but it cheap enough that it's not far off a set of budget built compounds. Just alot easier to set up.

The timing seems high for a street truck? I'm looking at going up in power on my dd. I'm send my pump to Seth to go over an do some minor tuning. What loss would be had running a lower 17 timing? Is the 24 gonna harm the motor? Do you have a video of what the power is around 1800? Also when the turbo starts to come on compared to stock? I'm contemplating going budget twins but this does look appealing. does the .70 cause high drive pressures?

We played around with the fueling via AFC LIVE and there was very little difference other than more smoke and higher EGT going from 85% of max rack travel to 100% rack travel. This pump has never been benched so we don't know what it flows. Also, keep in mind, the internet is full of inflated "corrected" dyno numbers, so much so that expectations are set a little too high for most turbo/fueling setups. This truck at a "national dyno event" would probably make between 550HP and 600HP. At our shop 5700', uncorrected, on our Mustang Dyno, it did between 490 HP and 508 HP on multiple runs.

This truck came into our shop with the timing set to 24*, it's an Arizona truck that never deals with cold weather starts. It has a fresh shortblock with wide 155* bowl pistons and is equipped with 155* spray pattern injectors. The pattern hits in the bowl as designed, and the truck runs extremely well. Based on the fact that there are factory Marine applications with this much timing with a similar bowl and injector setup, no 24* is not too much for this truck and we don't want the higher EGT and power loss that would come from dropping the timing to 17* on this setup. We don't have a video of power at 1800 RPM, but we can load the dyno so hard, it will make full boost and 900 ft lbs at 1800 if we wanted, it would just chug and smoke heavy at 1400 rpm trying to spool against the massive load at low RPM so the dyno can be manipulated somewhat to make turbos come on earlier in the powerband than they might on the street. This turbo is definitely slower spooling than stock, but the lag to power ratio is worth it on this charger. Compared to stock, I'd say this turbo comes on about 200 to 300 rpm later. Drive pressure is largely dependent on RPM range, at normal street truck RPM ranges 3000 rpm and less, drive pressure is excellent with the .70 ar housing. If the wastegate is tuned to stay close, drive pressure rises quickly in the 3000+ RPM range. With the wastegate open, drive pressure stays in the 10 to 20 psi over boost range till 3500 rpm, that's as high as we tested on this truck/motor/cam setup, your results may vary. However, compared to stock, this turbo runs much much better in the 2500 RPM on up range. Stock HX35 turbos really struggle in the 2500+ range.

To be fair, almost any compound turbo setup is going to have a wider useful power range than a single turbo so it's not really fair to compare....
