ok im lookin to get stage 2 injectors back in the truck soon and would really like to have the resopnse and smoke cleanup of compounds and be towing with them.
thinkin for now sd turbo with 1.0ar housing or my existing van turbo upgrading to a gtp38r one of theese days just cant seem to make up my mine what to use over it. gt4202 ? hx50 or 55? s400? i ran across a hx50 with a 17cm wg housing for a good price i would like something with a t4 flange so if i need to change to differnt turbo theres lots with t4
Something like a 1.25-1.30 exhaust housing would be decent for towing.
Why do you want compounds with stage 2's? If you want to tow with them, get a modded H2E or convert to the Super Duty charger setup and drop a 38R in...
FWIW, I don't know of any turbos with a T4 turbine housing that would be a "good" choice for an atmosphere charger... And there are just as many if not more options in a T6 Flange...IMO
I've got a Microsoft Excel spread sheat on compound and charger sizing that I'll try to go dig up. Charles gave the link to me, and he uses the spread sheet for himself.
Now I see what you were talking about on the phone Nate...that 500 is HUGE!!!
I would recommend the S475, the one straight off a Detroit Series 60, you can get them for $600 or so on ebay, i did, and found out it's not what i needed, lol. It's an 88mm turbine exducer, with a 1.32 T6 housing.
Isnt an S510 larger than the S598? (110mm inducer opposed to 98mm)
ive got a van turbo on the truck right now, so a gtp38r is a drop in for me, i was just thinkin the sequentials would be able to have faster spool, clean up more smoke and more efficent. but if i did save the money and go with a single the bb could be gotten quicker
ok the t6 sounds like a better way to go, like ya said much more in that range i was lookin too small
psj- ya still got the 475 kickin round?
holy crap the s500 is huge!!
ill see if i can get pics of the turbos on the 9.8MW diesel gen sets at work, i can probably get pics during our next outage in they dont let us in there often radiation levels too high at full power....
38R seems to be popular for the secondary,
as for the atmosphere, the bigger it is, the longer it takes to spool, but the more it puts out. it seems that a towing setup has the two turbos sized, relatively close together, but with the atmosphere large enough to pressurize the intake of the secondary efficiently.
Street setups have a slightly larger atmosphere, so it takes a little longer, but packs a bigger punch. It seems these work well for towing as well
Race setups tend to have ENORMOUS atmospheres... and pretty big secondary's too... IIRC I read that Zane of *** has a turbo off a 31L diesel generator as his atmosphere...
FWIW, i'm not an expert, but relatively well read.
A pile of cracked heads and blocks were stacked in the corner. Experimentation has its price. Zane gave us a quick overview of the $30,000 engine that pumps out nearly 800 horsepower. Two high-pressure oil pumps are stacked, one for each bank of injectors. A stock injector flows 120cc of fuel. The ones Zane runs push 500cc. Heads were modified to handle the extreme boost, like 90psi on the track with ETG running 1600 to 1700 degrees.
This kind of fuel needs lots of air. The primary turbo came off a 31-liter Perkins Generator. It's about 10 times the size of a stock unit. The second turbo is only twice the factory size. A divorced wastegate keeps control of the pressure out of the secondary turbo and dumps it back into the main turbo, so no energy is lost.
hmm...Interesting. I thought he said he never broke any blocks. Maybe we'll get him to chime in on this article...The press has a way of getting things out of context... That could have been a pile of PMR blocks with the CCV mod...
Not to let a Chevy beat a Ford, Zane Koch in Salt Lake City clocked the fastest time of the day in his 1997 Ford 7.3 Power Stroke--12.21 seconds at 114 mph--and that's on regular pump diesel. We stopped by the Wide Open Performance shop in Sandy, Utah, to learn some of his secrets.

It should be clear that the author simply misunderstood, or was merely incorrect in his thinking on the matter. Happens to the best of us from time to time.
Nothing more, nothing less. Unless someone has a better explanation.
LOL Funny I forgot about that article.....I still remember the look on everyones faces when that article was opened in the shop......no one had talked to said magazine and yet an article was there...lol yeah always trust the media.....
LOL we still to this day don't know where that info came from.....one oil pump for each head thats funny right there...
fyi the atmosphere is pretty large upwards of 105+
how is the s400 so much better than the hx50 the 400 only outflows the 50 by .04 kg/s which makes the hx 1368cfm and s400 1441cfm is the 73 cfm that substantial of a differnce? just dont understand all the compound sizing stuff and you want the small charge to dump into the exaust intake of the big turbo when its over a set pressure and the big turbo vents to the exhaust? would it workout to be running both turbos with wastegates built in? or best to have standalones? or one intergraded and one stand alone?
bwd uses a gt4202 or s300sx74mm or a 74,76 mm turdonetics
are theese setups not worth a turd? i just dont know on the setup and want to try to setup everything so if i needed to change turbos i am not 100% stuck with one setup
