gen3 twin ipr setup.

[4.0l sahara]

Well After getting my truck on the dyno with bill and letting him tune it. He just couldn't get it right. He spent a lot of time just working on the idle and trying to get it so it wouldn't stall when you hammered the throttle and let off fast. The single ipr just couldn't bleed pressure off fast enough. He had ipr DC under 5% I think. I'm sure he could explain it better than me. Well it looks like if I want to keep the gen3 I will need a twin ipr. So who has one and where can I get one? Or maybe somebody can make me one. I think it was HRT that made some twin ipr blocks. I'm also disappointed with the s468fmw she just didn't seem to have the punch that everybody claims this little turbo packs. I think 275's are just to much for it. May be time for a s471 with a race cover.

Can you post a screen shot of your ICP, PW, MFD and DC tables?

I can assure you the 468 has enough "punch". What boost were you making? Get your other problems fixed before you throw in the towel on the charger. A 471 is not going to be much of an upgrade anyway. We're you being dyno tuned?

:whs:

We have done the S467 with many sets of 300/200 and have had great results.

I feel you on the stalling. Mine does it at random. Runs super choppy after a hard run.

Ive had multiple tuners send files, never got it 100%. Ive just delt with it.

And Id disagree, your 275s are not to much for that turbo...

i like the sounds of this ^^^ close to my set up... what HP range are you seeing??

Maybe that's a sign that the GEN3 pump setup is a little "too" much? How about a stock dual setup or modified single pump? Kinda seems like putting a band-aid on a broken arm, no? How about that choppy shudder after startup?

Gen3 is def more than enough. The side effects on mine being a puller dont mattter much but it even takes some dialing in to get a high idle setting to not throw a cel.

The gen 3 is staying. It will be getting 400/400's and compounds the whole reason I bought the gen3. I have almost zero chop on start up.

It was tuned on the dyno by bill at php. Spent over 3 hours just trying to get it to idle nice and not cut out if you let off on hard acceleration. In the end he said the ipr was just topped out and just couldn't keep up. Maybe he will chime in. As for the turbo it made like 48psi and was screaming. I had the gate slammed shut with co2 from the boost controller so that wasn't a factor. No boost leaks as far as I know. Made a disappointing 525hp and 1100ftlbs.

I'm still in south Carolina but when I'm back in ct I'm going to look it over and dig into it.

What part of SC are you in? Just curious let me know if you need anything

 

[4.0l sahara]

I was about 20 miles south of NC on I95. Just got back to CT.

I thought swamps offered a dual ipr setup for the gen3. Maybe I am out in left field.

Hows that disappointing? With the 275s holding enough fuel.for.550, you are under a bit. What were you expecting? 625?

 

[Powerstroked162]

Jason (HRT) has the nicest dual IPR block that I've ever seen. I know he's done some work with the gen3 on another guys setup and had good success. I'd shoot him a PM

It had plenty of fuel left at wot to make more. next step will be to pressure test it for boost leaks. I'm pretty sure it has zero though. So people running the s468 what do you guys see for max boost. It has the fuel for 600 imo. I thought it would have the air too.

I put down 519@968 with my 468 250/200s couldn't load it good enough and only got 39lbs. But on the street I'm seeing 52+ over 3k rpms

 

[mattman347]

Mine made 658 on Jonathan's dyno after being tuned and on the street makes 50-53 lbs boost. I ran a 7.79@85 at the track so it's close to the number it made.
