Kc's hx52 talon 579whp at 23psi dyno at fwd performance

[swifteagle]

Just got done on the dyno car made 579whp at 23 psi clutch started slipping so we could not run any more boost this was on e85 and a holset hx52.I'll put some vids up later.

 

[kidtsi]

definetly a 800 horsepower car if you got enough fuel and you fix the clutch problem

 

[swifteagle]

On like the first pull at 15psi it made 400whp.

Get those issues figured out and turn it up. I want to see what that turbo can do at 40+ lbs of boost. Not 23.

 

[RvlutionMtrsprt]

What stroke, compression, and when did it hit 23psi?

 

[907dsm]

Dyno graph or videos??

Dang that's awsome! I curently have a HX-40 but have purchased a HX-52. Its not installed yet. The 52 is SO FREAKIN HUGE in terms of actual physicall size and shape and weight. Was charged on shippin for that thing, 49 pound package. Defanatley feels like it weighs fifty pounds.

What turbo did you run prior to the 52? I would assume you upgraded from somethin else as nobody just springs for the biggest bastard they make.

So what was your prior turbo? And after switchin to the 52 how much of a RPM loss was there gettin into boost? I'm personally havin second thoughts of puttin the 52 on my car. It looks like it will loose SO much street manners.

My current set up is a 60mm 6blade compressor wheel with a 12blade turbine wheel. True Holeset compressor cover and a bullsey power turbine housing that's T3 in and 3" v-band out. With Ross 8.8-1 pistons BC 280* cams and 2 huge custom made mannifolds my HX40 will do 30 psi by 4900RPM and a rev limiter set at 8500

So I bearley have a lil over 3500RPM of true balls to the walls usable power, I'm AFFRAID that once I switch to the big dawg HX52 that my lag is gonna make me dislike it. Its my assumption that, that same 30psi boost that I used to hit at 4900RPM won't be seen untill probably, oh, I'm thinkin 56,5700RPM.

That would put my true balls to the wall power zone less than 3000RPM of power. I don't like that idea to much at all.

Since I already have done Holset HX-35 and HX-40 and am soon to (maybe) do the 52 I'd like to know how it spools compard to the previous turbo? How is it on the street? The 52 comes with a T5 footprint. Did you just wobble out the holes to get it to bolt up to T4 flange? What kind of turbo header/mannifold do you run? Is it divided?

I LOVE the HX-52, the sheer size and looks of it is true bad-ass. But, I'm worried about spool. Was it worth it to you? Do you have any regrets? Is there anything you would change or do differantly?

I know what the HX-40 is capable of. People clear 600AWHP with it and have done EASY ten second passes. The fact that its still relativley "quick on its feet" to spool is what makes me be a firm beleiver in the HX-40. I'm scared that the 52 is gonna make me miss my 40... Any advice? Thanks, and sorry so many questions. Thanks agin

my motor is stock crank eagle rods wiesco pistons arp hardware bc 284 280 cams springs retainers and engine builder valves stock port head intake and tb. Its about 8.9.1 cp ratio.And yes you can just use a t4 manifold and open the holes up I'am just using a obx t4 open manifold.

What clutch/pressure plate?

Peak timing/AFR on the 27psi pull?

3rd gear spool?

Can't wait to see the video!

 

[swifteagle]

I'am not exactly sure where the boost comes in at but when I get to drive it I'll let you guys know. Here's the dyno sheet

The pulls he made are in 4th. The clutch is just a cheap xtd unsprung stage 4.

 

[habitatguy187]

On like the first pull at 15psi it made 400whp.

So 8psi added 180whp! Super impressive . Also nice to see someone max out an xtd stage 4 on a dyno, 579whp isn't bad for a $150 clutch. I wonder how far it would last in an awd car.

 

[swifteagle]

The car is awd I just dyno it fwd.

 

[tkelly27]

Is the SMP charger still at FWDP?

Really nice numbers. 400hp @ 15psi is awesome.

 

[LandSpeed-DSM]

What intercooler? Any water/meth injection?

This is getting me real excited for wrapping up my HX52/GSC S3 build.

 

[swifteagle]

Here's the link to one of the first couple of pulls. [ame=http://www.youtube.com/watch?v=vSgWQeWdVSY]Kody's AWD Talon, on Dyno made 600hp on low boost - YouTube[/ame]

The intercooler is just a cheap Godspeed bar&plate no meth injection

Thanks to Cindy/James and the guy's at fwdperformance.

 

[MarsaGSX]

Any updates??? Have you raised boost???any 35+PSI boost dyno numbers??
Thanks

 

[fosforito95]

yea and still havent gotten back to see at what rpm are you reaching full boost?

 

[swifteagle]

The talon has been on the back burner. I still need to make a wastegate dump finish the paint work and put a good clutch in it ect.So I have not got to drive it much but it runs good and cold start and idles good with the 1650s. its only running about 20psi right now because of the clutch issue and if anyone wants to donate a twin disk that would be great!

I'll have to take the car out and see but I think it hits 20psi by about 4500rpm

 

[swifteagle]

Update I got a qm twin disk in so I am going to start working on the talon soon.

 

[Miasma]

Can't wait to see, where have you guys picked up your hx52's. I'm looking and haven't had much luck

 

[swifteagle]

I got mine off ebay they sell them as used cores.

 

[airmail96]

Man those are some pretty good numbers I always wanted to run a 52 but never thought I would be able to push it to its limits .

 

[boosted-tsi]

The car is awd I just dyno it fwd.

I'm close to finishing my car and want to know what is needed to dyno in Judy fwd

 

[swifteagle]

I hope to get the talon finished up and back to the dyno by September. Then we can see what it will do on 40psi.
