Impressive vid.Car is running very well.

Figured I'd bring this thread back from the dead rather than start a new one. Carl's HX40 setup has recently run 11.3 @ 127 (before the dyno session) and dynoed 516whp at 32psi. Timing is only 16 degrees up top, AFRs are 12.5:1. Before hitting the dyno, we installed an AEM boost control solenoid. While setting it up, we saw 40psi and it spun all 4 drag radials from a 3rd gear roll. We couldn't leave it that high on the old cal. file because it was way too lean. Now that the car has been tuned and we have a clean base map, we can turn it up and the boost comp. should keep the AFRs in check. Full boost as logged by AEM is at around 4k. There's no sign of power dropping off up to 8k+, not bad considering it's in the bolt-on housing.

We took my car to Atco this saturday.

Bolted on some KSport Pro Drag coilovers - what a difference. In the cold weather the car pulled a 1.59 60 foot.

Best run was [email protected] - this was at only 12 degrees of timing.

Last run wasnt clean after adjusting the timing so we dont know what it could of done. There is always next year...

Here is the vid thanks to my boy steve...

Nice times, though will have to spend the winter .081 sec from a 10-sec run

516WHP is impressive and I know you've spent a ton of time tuning, but have you taken backpressure readings at the manifold to see if (or how much) the BEP housing is holding you back with the HX40? Much speculation has been made though have yet to see anyone that has actually tested it nor provided emphirical data to substantiate

At this point...I dont think the BEP housing is holding me back. Actually, we havent spent a 'ton' of time tuning. That is the main problem....with running my businesses and raising a family...I have little to no time to get the car out for street tuning sessions. We ran out of time on the dyno at Philly Dyno Works so never achieved full potential...the tune was conservative to say the least....also, keep in mind that Lex is a 2g guy...so that should tell you about my timing tables!

I have faith in the BEP housing...considering we went 105.50 in the 1/8 mile. We ran out of timing. On the last run I didnt get a clean 1-2 and bogged. But, with timing up - 3rd gear felt like a completely different car.

Atco is supposed to be open Sundays in Jan...so we will see if I can get her out again!!!

To be continued...

Like Carl said, it's far from having tons of tuning time. Before the dyno, we were fumbling through AEM with very little time here and there and reached a point where we realized it would be better to get it on a dyno and have someone who knows how to set up the microsec/bit, boost comp.,... correctly get us a clean baseline to tune from. In doing so, the car went from 491whp on our tune to 516whp on the new baseline, at the same boost and with richer AFRs and less timing.

After that, we never played with it anymore, just hit the track again. After a couple passes we realized that on top of the already conservative (for C16) 16 degree timing setting at the 32psi load point, the new map was set to bring timing down to 12 up top on the higher load tables as a safety net. On the next pass, we bumped it to a still-conservative 16 up top and like Carl said, the car felt much faster but it wasn't a clean run. As usual, we were out of time.

Regardless of the power it's putting down, the bigger picture is that the Holsets are cheap, bulletproof, can be bolted on without the need for a $600+ manifold and custom o2 housing, and the thing spools like a turbo half it's size. Even if your only goal was to have a fun street car that runs high 11s, I'd still recommend this turbo.

can you post the dyno sheet?

Here it is..this is the 516whp graph...we ran out of time on the dyno since we started late. We are going back down early spring to fine tune...but, have already started tweaking it at the track.

You you remember at what rpm you hit the 500whp mark?

I am wonder how fat the power band is up top.. How many rpms are you over 500hp?

Here ya go...

Wow and this is at 32psi AFR in the 12's or high 11's?

OT And with that type of pwr and drag radials your having no probs with the ACT2900 setup?

With these #'s I think I'll keep my hybrid(HX40/35) setup after all. Would you guys say it's a keepr. It also has the Turbine housing that bolts to the turbonetics exh mani. 35mm TIAL wastgate mounted on runner #1. OPINIONS? Especially concerning my Holset?

That Dyno plot looks kinda strange for a 500WHP run with peak power at 7K

Yes looks Very Peaky!!!!!

Sounds like this http://i18.photobucket.com/albums/b148/nanokpsi/Picture003.jpg

I'm guessing his is more from a small hotside and not a 100mm stroke limiting his top end, although mine would be better with a good exhaust mani also. Mines just measly pump gas though.

This was a baseline tune on the AEM, timing was hitting a peak of like 12-13 degrees above 6k, probably only like 5-6 degrees at 4-5k. Once we got aggressive with the timing curve, midrange and top end picked up ALOT.

First of all i would like to congradulate you on those numbers.
Sry to jump in but i read most of this thread and im a little confused with the turbo i bought.
Can anyone tell me some more inforamtion on this turbo?

Thanks

I know this would be really crazy. But isn't that new FP exhaust manifold angle slightly for better fitment of very large turbos? Just imagine a holset/bullseye turbo beneath a force performance manifold. The nay sayers are gonna love this idea. Would this set up clear the water pipe without the use of a hammer?

According to FP, their new manifold is a dimensionally identical placement to stock. They designed it to optimize their FP30 turbos, which clear the water pipe already. My S256 with Bullseye bolt-on housing clears fine as well. The HX40 is an unusually large housing.

You need to remember that when you move the compressor cover farther away from the block you move it closer to the radiator, so you can only go out so far.

I normally just browse the forums, but I had to throw in my .02 on these turbos. I upgraded from a 50 trim with bolt on housing to an HX-40 with the bullseye bolt on externally gated. I have just about all the mods you can do to a DSM performance wise except stroking. I have to say this turbo's power increase over my old turbo is unreal. Without a doubt the most impressive power upgrade I've seen on my car since I began modding. What really amazes me is the amount boost/timing that they are capable of on 93 octane. Currently I'm running 25psi@18-21 degrees of advance with ZERO timing pull from knock. I've not made any passes or dynoed this turbo, but as a reference my 50 trim pulled 11.8s@120 on race fuel and this turbo is significantly stronger on pump gas. After modding and racing my dsm over the years, I can definitely say this will be the last turbo I buy for it.

If anyone knows anything about the turbo that I posted about in this thread please let me know. I think it is a HX50. Thanks, Keith.
