Reeves' OMNI GLH-R Update!

[contraption22]

Just awesome!

[Rampage16V]

Yahoo!!! Gotta like that!!!

I heard a rumor...something about 577whp and 552wtq?

Wait a second, those sound like 2.2 #'s to me. What happened to all that 2.5 torque? lol

Will be very interested to see the peak torque and HP on that run. Great job bro!

[2.216VTurbo]

Wait, when did JR go to a 16Vmotor?

[wheming]

Is there an easy way to get a breakdown summary of your build? Or do I have to take a day off from work and read all 1100+ posts??

Wierd, I've had Great results with internal gates! Never a problem. External gates on the other hand I've had to change springs and fart around trying to hold boost stable.

Just goes to show you, two different ppl with different experience = different results! lol

The internal wastegate set up on the SC6152 I have allowed uncontrollable boost creep above 5500 RPM!! I tried and checked everything I could think of to no avail. I can say that with a 4" exhaust system, back pressure wasn't or at least shouldn't be the cause! BTW, awesome car and videos James!!!

Tis true!

Are you saying the precision turbo's have an inherent Flaw in there wastegates? The Holset I'm running is unported at the W/G. IF I open the 4" dump on my 20psi street tune it will creep to 25+ very quickly, but with the dump closed and going through my full 3" exhaust it's solid at 20psi. If I go to the track where I run 35+psi with the 4" dump open, the boost is rock solid as well.

IF I wanted to run 20psi with the dump open, I Don't need an external gate, what I need to do is port the internal one Larger and/or "bias" it to Flow More Through........that's it.

Now, if your saying that you've ported the SC6152 as large as it will go and it still have uncontrollable creep, then the turbo was made with too small of a W/G, simple as that.

So the problem has nothing to do with internal vs external, it simply has to do with the Right size W/G and correct exhaust path through it for the application

awesome numbers. Who would have thought 20 years ago, a 4 cylinder Omni would make over 600 engine hp someday! That would be crazy talk. Now if you don't have at least 500 whp you probably won't make the quick 8 at a sdac event. !!

I thought I saw a vid of this some where. Sick Tq! What was peak power at?

I just measured the IG on the 6152. It is around 20mm at most. It probably could be ported out some and just move the creep up higher in the R's, but it is not worth the trouble to me. I'am going EG. As good as my car ran (8.30's @ 90mph- 1.9's 60's on pure street radials) I had the boost limited to around 23psi and that was in 3 stages, and then I was bleeding off all the boost that was caused by the creep (who knows how much) out the BOV valve (I know, an awful thing to do). But I least I was able to do some testing on the new combo. When my car runs again with an EG installed, it will be much much faster I'am sure!!!

Congrats James. That is an incredible feat.

[mopar-tech]

Nicely done James, makes me want to get back in it but I have a few things to get settled first.

Saw the video over on that facebang site. Nicely done!!

[BadAssPerformance]

Nice work James!

[Reeves]

Thanks guys!

Wow!!! Awesome dyno pull!

[Reeves]

Those torque numbers are probably off. You can hear the tires squealing in the vid. Couldn't keep it from doing it at torque peak.

[Shadow]

Been having the same issues with the Charger on the dyno. It hits just over 5200rpm and won't hold the tires at the roller load and at the boost level I ran at the track

What size and make of tire do you use on the dyno? Still on the clutch you had at SDAC?

[GLHNSLHT2]

nice Numbers, but wow I didn't know you could still record in 240p on anything Must be a backwoods kentucky phone
