After long months of heavy work schedules we finally got some time to get the motor going. It has a pretty stout thump for a turbo motor. The Q16 fuel has a nice aroma coming out the exhaust. The goal here was to fire the motor up on the "old" bank to bank ECU. We wanted to make sure there was no leaks and the motor ran smooth. Now we can swap ECU's to the sequential unit which requires harness mods. In the comming weeks we will install the boost pipes, intercooler, intercooler chiller tank, boost controller. I hope the images turn out right I'm learning the photobucket thing

Ahhh, much better! What size injectors are you using? 3" downpipe? MBHD

What size turbo do you have? Is the turbo going to change your RPM range, bet it does. Looking good! Thanks for keeping us posted. Tom

Tom, it is a turbonetics 78mm BB. I'm not real sure if it will change the rpm range that much. Our nitrous motor made all the in the 5000-6600 rpm range. We kept the turbo kind of mid size to make it spool easy. It would have be cool to put a 88mm on there. We think you are reaching the outer limits of the durabilty of the comobnation. We decided to limit our combonation 1000-1100hp because that is where the fuel pump, intercooler and some other componets are rated to. Heck, 8.60-8.80s @ 150mph in a 70yr old truck is fast enough for me

The thing you are going to notice just how much RPM the engine is going to want to RPM to. It will seem it wants to keep on reving higher & higher. Your camshaft will want to go to 8500. Not sure if your 4.120" stroke will want to though. Anyways, you will definately like the turbo engine over your nitrous engine when you get it all dialed in. MBHD

MBHD Yea, this long stroke never really did like to rpm. That's is why we went with a smaller turbo. HP and RPM will go faster but, mild RPM and torque will live longer.

My 2 cents and yes my turbo motor is way milder than yours and will be less powerful by about half and isn't running yet. If there is room you should consider going to a 4" downpipe. Everything I've read and everyone I've talked to says downpipe diameter has a measurable effect on spool. I'm going to use a 3.5" downpipe with my 62-1, which was recommended by the guys at turbotechnology in tacoma. A 78mm turbo is no joke. It wants to breath.

The exhaust after the turbo is critical since a turbo motor needs to gain RPM as an N/A motor until it gets to boost, but mainly the exhaust after the turbo acts as a restriction and increases the back pressure in the exhaust manifold. Any back pressure effects the camshaft valve timming and reversion in the combustion chamber and intake, which makes it very detonation sensitive. The first 18-24" is the most critical after that the exhaust flow changes and can be smaller unless it's a race only then keep it big and dump it quick.

If in fact you find that the stroke is a limiter where will you go with it? What a clean build! All that in a small space and the hood still fits? You should sell rides.

My down pipe is 4" about 24" long for racing, for street a 4" pipe and a 4" dynomax muffler to the rear end, if I want to carry on a conversation in the car I cap the 4" pipe after the muffler and a 3" pipe exits past the left rear tire. Working on a system that will open the 4" pipe automatically when is goes to boost.

Harry Thanks for the info. We bought a data logger a year ago and decided to get the proper pressure switches and EGT temps to make a quick learning curve. I'm sure we will make quick changes if needed.

Mighty6,
I did not mean any harm on posting my downpipe if that's what you mean by picking on your engine.
Your 3 " downpipe will work just fine, if you later think the downpipe is holding back power,you can always whip one up in a couple hrs,you guys do great work!!!!!!!!!
I would love to get my damm engine running,I just do not have any time. Wife works a different shift than mine,kids are too young to be left alone while I work in the garage..
So, most of my life is watching the kids , working ,typing on the comp,living my life vicariously through your guys rides,then going to sleep. Yes ,my life sucks as far as getting anything going/done on my car & motorcycle projects.
Plus my wifes has depression & that makes it hard on all of the family.
So, Mighty6 ,,,,,,,,,,not meaning any harm. MBHD

Looks like you have to many projects. I wanted a Fazer 700 at one time. I have a super clean 2002 Hayabusa with all the basic bolt on mods. I have never taken it to the track because if I did it would end up like that blue truck. It will be never fast enough and I do not need another money pit.
Now back to original topic
I have some new parts that I will post this weekend.

Harry We dont have room for a vega box so we are going try a Unisteer box. We are still useing the 1936 steering box (rebuilt twice). It is starting to get a little loose

A couple of things we are working on right now. The AMS 1000 boost controller will be used with co2 to controll the waste gate. You can ramp boost in and out depending track conditions or wheel spin. The air/water intercooler chill tank with a bilg pump installed. [img]http:// [/img] [img]http:// [/img]

OK, enough w/this jibber jabber,we need video of it running I'm just bored, no pressure. Hey, those parts look nice. This is the old school boost controller I have http://www.theboostdepot.com/index.php?p...emart&Itemid=26BTW,,,This is from my friends website. MBHD

Those work well on motorcycles. My brother has one on his bike. Can you ramp in boost?

Those work well on motorcycles. My brother has one on his bike. Can you ramp in boost? Yes, you can,it has a lot of features. Here is one installed in a street car from a local shop NRE. 2.30 seconds into video http://www.youtube.com/watch?v=Ad8g9IfWxKIAdjust for poor track conditions,etc. The MSBC-1 has the following features: *Six stage programmable boost control. *Useful for street or drag applications. *0-60 psi target boost range for each stage(1 psi increment) *Up to 18 different Ramp settings to control how fast boost is allowed to build. *Launch stage for drag racing. *Shift input for automatic stage selection for drag racing. *Front panel stage selection by driver. *Actual boost readout during boost control. *2 Analog data recorder outputs-Actual, and target level. *2 solenoid drive outputs-One for an increase boost output and the other for decrease boost output. *Can be used with single or dual port wastegates. *Uses electronic pressure sensor to monitor and control boost. *Will force wastegate to produce preset target boost level even with air density, load, or mechanical variations. *Can be used with manifold pressure only or external pressure source for control.

That doesnt seem to old school to me. It will get the job done no dought. I thought Nelson Racing was in Florida for some reason.

Mighty6 is fresh off the chassis dyno. I made some pretty decent numbers ...... I want to let MBHD sweet a little bit No sweat here LOL. Glad you got it running! All I need are details,how much boost & what rpm you stopped @ . Are you making more power than the Nitrous set-up? Your combo,is different than mine other than we have the same cylinder head. I am sure it runs great & I believe this would be the first turbo EFI Kirby Sissel head running. I can't wait tell I build my ultimate combo! Ok,, I give,,,what did it make! I need to know! NOW!!

717 rwhp @ 6200 rpm 813 rwtq 5000 rpm at 19 psi. The turbine housing a/r is too small .96 and would not let the motor make power past 6200 rpms. We have a 1.15 a/r housing on order that should make 50-100 more hp. An 88mm T6 combo would make more all out power but the responce is unreal with this combo. It makes 70 more hp, 200 more tq. It is a beast compared to the nitrous motor. My understanding is that our heads are the same. Douglas has the first EFI turbo setup. http://www.youtube.com/watch?v=baj4UmT02RM

Do you run a pressure gauge on the exhaust( before turbo)?
Those are some fantastic #'s!! This combo will be way easier on the engine and on your pocket book over time. Holy snikees that is alot of power. Tom

45 PSI, that is alot of backed up exhaust. I see why you are going to the bigger housing. I'd love to see your dyno sheet.
What rpm range is the pull and I noticed from the video, the rpm's rise very fast. How many RPM per second is the dyno set for?
Are you going to be able to hold it down at the track? It will be fun. Tom

[quote=MIGHTY6 Douglas has the first EFI turbo setup. http://www.youtube.com/watch?v=baj4UmT02RM [/quote] I know that Douglas was fisrt ,forgot to say in the U.S. Those are some good numbers. Congrats! Yes, for a drag vehicle & your engine size a .96 is too small. What is the trim on your turbine wheel? Have you driven it on the street? What is the stall on your converter? What are the exact specs on your turbo? Just curious,I know I will not be as big of a turbo,smaller engine. MBHD
