I know some wanted to see how a largish turbo fit. Here is the finished result. Ignore the dirt on the car, I do.

 

Is that a quick spool valve thing for the t6 flange? How long have you had it on and were u using it in the last vid showing spool up of the turbo?

 

dunno what you are talking about my turbo is t4 flange...

 

**** now I'm confused?

 

damn zombie, that thing is gargantuant....real quick...for the two of you....what stall are you guys running? and how is it driving the car on the street? depending on how tall the stall is?

 

Had a 3200 in my 4l60 and now a 3000 in my 4l80. Both wrk really good for me since they are both lock up convertors. They are both super streetable and I dd.

 

So ZOMBIE is that one of those valve things? I would like to know if it wrks as good as some say or not.

 

Zombie you little.....lol you have a quick spool valve dont you??

good work though mate. did they make much difference??

Chris.

 

That's a nice fat turbo. Looks good

BTW, have a seep in the return pump lines? See the nice oil slick on the concrete underneath it.........

 

Looks like the turbo from one of our Detroit Series 60's at work. That thing is large. I think we all need a video please.

 

LOL, this is probably the first time zombie has seen the underside of his car also, so how would he now what that thing is? And no, "what ever " that is, wasnt on in the last video. I was under there monday night doing some stuff.

Still working out bugs in it though. We missed the arm distance by a nat, and the first acuator wouldnt work at all, so I used one from my turboed zx11 but it does now.....

Still waiting to see the logs. Priliminary feeling is good, but doesnt mean anything, we working on results and numbers.

 

how is ground clearance with taht beast

 

That turbo will be on another rear mount now......guess someone is copying you . Wonder if the member will speak up??...lol

 

Nice thats look badass.

 

so the SX80 turbo spooling almost as fast as the last turbo (s80 wasn't it) is not thinks to this valve? thats even better news! lol

Really hoping this makes a BIG diffrecne to the spool. hmmmm wonder if anyone from STS is reading this.

Chris.

PS how loud is the car with the bulet muffler on there??

 

It has 4 inch echuast post turbo with a 4 inch bullet, Its pretty quiet, but still a hotrod. A softer sound then a stock cam car with headers and a cat back.

It looks like the valve may be much better in the 0-5 psi area. Once it reaches 5 it pretty much takes off with or with out the valve. The 0-5 area, maybe in the 30-40 % faster area. IMO it drives like it s got a 67 on it. I might be delusional though, so zombie will have to post the numbers.

 

thanks 1320. be nice to see aoverlay with and without the vavle....

Chris.

 

the quickspool valve does wonders .. i have a local machinist to me thats whipping them out so ill have one on my camaro soon too =)

 

Thats what zombie is working on, with log files. We just need more data with the valve. He has plenty of before files, even after the turbo change. But we just did the valve monday. Last I talked to him , he was averaging log files, to get as much data as possible, but needed to drive the car more to more post valve data. He has probably been out everyday this week...lol

So far, it looks like it could be different for every application. Zombies car, if it spooled slow, it was from 0 psi to 5. Once it reached 5 psi (with or without) the valve it will take off anyways. So the place for improvement was really only in the 0-5 psi area. There probably are improvements above that, but since it takes off even without the valve at 5 anyways, you probably would never feel that change above 5, but might see it in numbers, from log files, area under the curve on a loaded dyno, or in short times at the track.

If someones turbo car, is lazy from 0-8....then takes off, they would probably see and feel a bigger change. So, those with big turbos will probably feel the biggest change.
Since I build turbo street cars that race, right now, I will not do a new build without using one. If I buy any turbo, it will be a divided housing just so I can use one, no matter the application.
Im also working with the maker to try and get a t5 flange for the ht3b turbo. We use them on compound turbo cummins, and there is a divided housing. Maybe i can see 40 psi on my cummins at 1500 rpm......that would be neat and keep egts way down, lenghting the power in each gear. For towing it looks real promising.

The other option.....is use the ht3b on a gas engine like a ls engine. They are 80 mm turbos, with giant exhuast housing, and with teh valve may make it perform well.....and they are about $450 new.....so it may be possible to get into a 800 rwhp turbo that spools decently for the street for about 650-700 $ total, that is near indistructable. Entire 800 hp turbo engine and turbo parts could be done for 5k maybe.

 

some great ideas there 1320. i guess the big Holset Exhaust housings would also reduce the back presure once upto full boost. this would net you more peak power wouldn't it?

anyone know if the import guys are using these?? bet they would see a real gain with the small engiens/big turbos/higher RPMs.....
