    Holset Turbos, PART 8

    Just saw this and was wondering if you happen to have just one 255 FP? I was running 35 PSI on the HX35 w/1000cc injectors on E85 and seeing tops 80% DC @ 11.7:1 AFR and 18* of timing. I was running mid 11's 11.5-11.6 back then as well. It just sounds like your fuel pressure is dropping or...

    King Kams vs K280s

    I've been away for a very long time. I have the KK's dialed in on the new motor. I've been away at school for the past 6 months for another air force job. When I return I should have the car done by November sometime and on the dyno in December. I do plan to see how far these cams go before...

    Holset Turbos, PART 6

    I like it not to surge as much. I had a decent amount of compressor surge on the HX35 with BEP housing. It was usually when I would hit 8-12 PSI during part throttle cruise. And of course the subsequent stall I would hear when I had to lift off to come to a stop light. Man it really wasn't...

    HX 52 1G build-up

    I kind of don't stay focused. I do something until It's either finished or I run out of parts, or I run into a problem that I can't fix right then. Then I move onto another system until the same thing happens.I have the motor all put together now minus the manifolds. I'm debating on...

    HX 52 1G build-up

    Thanks for all the comments.Yeah the One FMIC you can see is my old one. The new one is behind the radiator and you can just see the outlet sticking out behind it. It's the same size but is 4" thick as the old one is 3".I'm going to kept the power down below 700HP I think until next year...

    HX 52 1G build-up

    Well after a few years of collecting parts and starting and stopping the build of my HX52 the day of finishing it is finally approaching.I got my HX52 back in 06 maybe even 05. I had already built 2 cars with a HX35. The Holset's are just great turbo's and they just work. I had popped my...

    Oil squirters and stock internals

    First off oil squirters are their to cool off the piston. The rings are not cooled by the squirters. They may see very very minimal thermal transfer but almost all the heat goes into the aluminum piston and not the steel rings.I would not sweat it. As far as the low compression that is...

    New cams low vacuum

    You have to much valve overlap if your definitely sure it's not off a tooth. I would get some adjustable gears and actually degree in your cams properly. Then see what your idle vac. is which I bet will still be pretty low. Then try advancing the exhaust cam just a tad like 2* and recheck...

    any dsmer in kansas

    I'm in Wichita. Had my 1GB down for a major overhall for the past few years. I'm just about finished putting the motor together. Almost finished running my fuel lines and have my duel pumps installed. The HX52 will go on and it's just a bit of wiring and some IC fab work. I hope to have the...

    Holset Turbos, PART 6

    And that is still to much oil pressure for a turbo. That is why I'm saying it's a waste. I did lower my upper end oil pressure but past 9K I'm actually wanting to maintain the 10 psi/1K rpm addage for proper oil pressure.I went with a FFF Bracket on the last build and it worked better than...

    Holset Turbos, PART 6

    I built a 2G w/ 6bolt with my old HX35 w/BEP bolt-on housing. I feed it from the head. Motor was running no balance shafts and the forward facing oil filter housing. Had zero issues with oil pressure. The same turbo running the oil feed from the OFH unrestricted with -4an feed line the turbo...

    Holset Turbos, PART 6

    I think you might be running out of fuel pump. Are you still running the stock fuel filter? Might want to replace it if it's not been replaced yet. Also might want to make sure that your FPR isn't leaking internally.FYI I was running 32-35 PSI on a completely stock long block with the HX35...

    Holset Turbos, PART 6

    Wow I'm in my basement for a few days and this thread just explodes. Ok let me clear up a few things I noticed where wrong.1. You can't add your boost to your base fuel pressure and try to calculate added fuel injected. The reason for the raising rate FPR is that the injector has positive...

    Holset Turbos, PART 6

    Porting SS is a HUGE PITA. It's a lot of work and time. I must have spent about 3-4 hours working on my 3" O2 housing to match the outlet of the BEP to the O2 housing. It still wasn't perfect but I was so exhausted and I already was seeing the actually 3" pipe through the work done on the...

    * * I need a list of everything that can cause fuel cut

    You can pop a HG because Fuel cut will cause a very sharp lean spike that also brings some pretty damaging detonation. I've personally seen it happen. Guy kept wanting to show me his fuel cut.

    It's $400. I got from ExtremePSI. I try to get everything from them. IMO they have the best CS and decent prices. Here is a link to the dampener.ATI Super Dampener

    * * I need a list of everything that can cause fuel cut

    Here is a stupid sounding question. Do you have your breather tube attached to the intake after the MAF? If not or you have it just venting that would definitely be a large part of the problem. It would just be blowing air through the PCV and out the breather. It could also explain the trims...

    Holset Turbos, PART 6

    On my H1E the TH outlet v band is slightly larger than 3". IE. I tried to put my 3" SS V band on it and the clamp is just to small to work. I think you could mill it down to get a 3" V band to work. The stock Cummings down pipe is cast so you really can't use that either. You can always get...

    Holset Turbos, PART 6

    I really don't need a dyno to tune. I usually can get a very decent tune in about 30 minutes of driving solo. With someone else doing the driving I could nail a dead nuts tune in probably an hour of driving. But this is going off of maps I've already built previously and already have the...

    Holset Turbos, PART 6

    Just updating. I finally got almost all of my parts. I had to cut a few items that I wanted off my list to accommodate my finished basement project. So here is what I have and going to start finally getting together after like 3 years.HX52. BC 288 Cams, BC Stock Size SS Valves, BC Springs...

    Electric Boost Solenoid Issues

    Well if you want to run both nipples hooked up I would try it this why. Run manifold boost source to the bottom nipple. Then pre turbo boost source to the soloniod's COM's port, then the NC port to the top nipple.

    You chose GT35r or holset hx-35/40?

    I ran between 32-35 PSI on a HX35 w/BEP housing on 91 Pump. It was an animal. Long block was completely bone stock including the cams. My buddy had a 90 AWD with HKS 272's and I think a 57trim turbo w/HKS external gate. Pro tuned he ran consistent 11.5's. I was never able to make it to the...

    Holset Turbos, PART 5

    How do you plan to route your water pump inlet? That thing looks like it is sitting way back on the block.An easy thing to do to get it further out would be to mill the head side of the exhaust manifold with like a 5* more upward angle. That would put it out plenty far enough to probably...

    Holset Turbos, PART 5

    Man if you are going to run a top mount might as well put at least an HX40 on or bigger. It would seem a waste of such a nice manifold to run the "small" turbo on it.BTW I just ordered almost all my stuff for my HX52 install. Running a DNP T4 44mm Manifold, JMF Drag intake, Power 75mm TB...

    Preliminary HX52 datalogs inside

    How are you running out of fuel at only 16 PSI with 1150's? Is it your fuel pump running out of steam? It would be so much nicer to have an electric fuel pressure sensor to datalog your fuel pressures to see if it's pump or injectors.

    Bw s259 on the Dyno

    Would have to have full size spare then especially with a welded center diff or spool. Screw A/C, P/S, Spare, and Bumpers. :thumb:Nice numbers man. Gratz on winning the dyno day as well.

    Need advice on turbo selection

    TY. I've been away for sometime. I didn't even know they finally came out with V3. Did they add the GM MAF code this time? I wish the originator of that got his credit but :shrug: . Oh then you should be ok with your ECMLink. I still personally hate how they use sliders. I hope they got...

    Need advice on turbo selection

    If ECMLink is a more sophicated airflow intercepter/manilipater like the AFC is then I would go AEM now. If you do have control over timing and fuel then you should be ok. Cause you are really going to be running around 15-18* of advance at those power levels, maybe a tad more if it's tuned to...

    Need advice on turbo selection

    I personally wouldn't steer anyone away from a Holset. You just have to realize they spool up very fast once they reach 8-10PSI. They can handle a lot of abuse ie.. compressor stall and surge, and still kept on ticking. The only bad thing I've read about the HX52 that was negitive was a 5.7...

    Arias piston ring gap

    Ring flutter will break ring lands. I would always go with what the piston and ring manufacture suggest. I wouldn't go smaller but going slightly larger for high output applications is usually good assurance. I could be wrong but I believe a good "Rule of Thumb" (and yes it should be "rule of...

    Need advice on turbo selection

    Hey Jshuman. I'm pretty sure you might have thought about it but I'm going to say it anyways. What are you going to do for your fueling? A single 255 can only support around 550 HP tops. You going to run duel 255's? Maybe get a JMF fuel cell and run something like a A1000? Then you have to...

    Stock ECU Native Wideband Review

    you can't put the LC-1 in the stock location. After a full WOT run you will get an overheat error. Most controllers don't have an overheat function and will just give you the bad data coming from the overheated O2 sensor. That is why you are instructed to mount it further down the exhaust pipe.

    My low cost high compression daily driver E85

    Wow. Well no. 14.5:1 isn't to far off from diesel compression ratio's of like 18:1 which is an average CR. You also have to realize that with higher compression ratio's comes worse gas mileage. It causes higher cylinder pressures which requires more power to get each piston to TDC. It's...

    Valvetrain resonance/rattling

    Timing belts don't chip. If they are to tight they will whine. I've never head a timing belt chirp. If it is the timing belt chirping I would replace the belt and the idler and tensioner pulley as those could chirp I guess you could call it.

    Tial BOV Spring swap VFAQ?

    If you happen to have some machine screws around that are pretty long it's much easier to use them to get the cover down and then install the short screws. That is how I do it. On the WG 2 1 bar springs are very very hard to compress by hand or even when you are standing on it tring to line up...

    Need advice on turbo selection

    I didn't read the reply cause you said you are getting your motor from FFWD. Talk to FFWD about your goals. They definitly know how to build high HP DSM's. I've spent a few hours on the phone when them a few years back for a customers build. IMO if I had the money I would have a fully built...

    Smoking after new head install good compression

    I had a buddy running stock exhaust that had a turbo just puke a ton of oil. It took a good 3-4 weeks before the car stopped smoking. It also had perfect compression (175 across all 4). But I've also seen a brand new rebuild head with new guides and improperly installed valve seals smoke the...

    Valvetrain resonance/rattling

    The thing is you are not explaining the noise throughly enough for most to understand what it is. And the Harmonic Dampener is either good or it is bad. It is currently failing but not the problem is not a proper symptom. The rubber could be pushing out the front and it hasn't broken yet...

    Ceramic coated bearings?

    IF you think about it your bearings never should touch anything. That means your main bearings should never be in contact with the crank. If the crank does happen to hit the bearing surface than it HAS to be replaced. That goes for pretty much any oil film bearing. The actual oil is what is...

    My low cost high compression daily driver E85

    You need to see if you have a zero piston to deck height at TDC. If the piston tops don't come all the way to the top of the deck that will add more volume than you are calculating. I would also run the thickest MLS head gasket I could find if it would indeed be 13:1 CR with the stock...

    6bolt swap info (search not working?)

    Well being as you've done all your research and are asking some pretty basic questions I'm surprised you didn't get heavily flamed.It's just a basic remove old motor and install new motor. Use black top CAS. (you'd do that on any 1G DSM) I personally don't care for the 90 oil cooler. I...

    Trigger plate on a six bolt swap

    Pullied head for HG and cams, how does the motor look?

    It's not the buildup of crabon/crud that would concern me but the color of them. It looks like those valves where getting pretty hot due to how white they are. That is usually caused from either leaking valve seats or to narrow of a valve margin. Usually high milage motors have semi white...

    Stock ECU Native Wideband Review

    btw it's been a few years since I've messed with the EPROM ecu but I think you actually need to widen the set points for closed loop. I think it's actually over correcting now if you don't change them. You are going from a 0-1v signal to a 0-5v singal and thus would also want to move the...

    fuel efficiency tuning

    If you are after sole MPG then don't run e85. I've gotten very good results running 15.7:1 and around 38* of timing. but that was in 5th doing 75mph. You'll want to change the OL set points for the TPS% and airflow. When you are fine tuning it's definitly best to be a passenger, and have the...
