Almost done, need 1 quick bracket for the charge tube running down low, figure out where to put the heater control valve and the coil. Of course the a/c lines need to be run and the inlet piping/filters, but it should run in a day or 2.

It runs.

Need to button a few things up, video soon.

Cool, but HOW does it run?

like most IC engines :P

I need to bleed the front brakes (removed the line lock for more room and shouldn't need it now) before I get too froggy with it. I did roll out into the culdasac and power brake till they spooled though, that was a fun sound. With all the gear this car has with the low gear OD it's hard to get it to spool before the wheels break loose though.

maybe a little cleaner pic


Took it around the block, I've got an exhaust leak on the dr's side, thought I found it with 1 of the v clamps slightly misaligned and the wg left a little loose, but still there. Barely any gas in it so I only went around the block, was able to build 1.9 psi at 1/2 throttle for 1 sec @ 2450rpm according to the log. Need to get some fuel so I can get out in a safer place to see what happens. Power braking won't build boost, the gear in the car makes it too easy to break them loose, don't need boost to do it

Even with the exhaust leak it does sound cool when it starts to spool. Makes some noise on closed throttle too- I don't have a BOV, figuring the 5psi I'm starting at with an auto should be safe? Lot of OEM cars run that way.

My poor heater control valve is seeping, it's been epoxied a bunch of times, trying to get it patched again. I do have a metal style one from a different application that might work.

looks nice
where did u get the merge pipe 2 into 1 to your t body thanks

Columbia River mandrel bends has that short v, I welded onto both ends.

where's the video lol would like to hear an see her in motion.

I need to figure out how to mount the camera for a fun shot, it's no big deal just idling in the driveway :P I do have a car dock for my phone but I'm not sure if the lens is covered when in it, I need to check.

Did you ever get the pics of the paisley benches that I sent you?

yes i did thanks. but they are a little worse than my original bench but i do apreciate it.cant wait to see the fury in action she's sweet

Ok, here's the video

http://youtu.be/0jYcPAGPB48

the exhaust leak is bad unfortunately and makes a lot of noise, will have to address that this winter. I didn't use gaskets, just copper RTV on the manifolds and I think that may have been a bad idea when the heads weren't checked for trueness.

The video is pretty close to WOT, it kicks down so that's deceiving, but it does seem to run pretty hard It hit 6.7psi at one point on my 5psi springs, will have to keep an eye on that. . Got to a little over 5.6psi at 4500rpm and 75% duty cycle. I don't know if my regulator is uping the psi, I need to attach my gauge on my braided hose so I can see it while driving temporarily.

I thought I broke it on the full boost run I did after the video, lost the boost gauge and it started running like crap. Luckily it was only the vac line that blew off.

This is definitely addicting

So far my impression is these turbos are NOT too small for this application. It's so eager to downshift it's hard to tell, but giving it a 1/2 throttle squeeze in drive brings on the boost pretty quick, but it is not instant or light switch. It feels just like I'd want it to really, so it may all turn out quite well. Because of the downshift it's hard to tell yet where the boost threshold is, but it seems to be somewhere around 2200-2400.

I did weld in a bung to do back pressure testing, I want to do that this fall as well to see where it's at.

Get it up to a speed where the transmission takes a hard jab to kick down to second gear and roll into the throttle. You'll feel how the boost comes in. It's interesting to feel your rate of acceleration, well, accelerate as boost builds.

The hot rod was about as tight as reasonable on a street car. About 1/4" of throttle at 60 mph in 3rd gear would build boost and I'd be close to 90 mph by the time I got around the truck I was passing.

You can also lock it down in 1st gear and see where the boost builds. That's a bit deceiving because the gear multiplication doesn't load the engine as hard and it revs easily.
When doing that, the hot rod would start making boost by 2800 rpm and the car would be sideways by 3200 rpm.

This car is no 700hp freak, but it's a pretty satisfying drive right now


I can be rolling about 10mph in 1st, nail it, and after a 1-2sec the turbos will spool and it will boil the tires, which is the kind of shananagins I was hoping for. Will be interesting to get to a track next year, it certainly drives like a 'big' 440 now but with the mellow little 383 the rest of the time. If I can eventually drop down into a smaller cam and add more boost I'll be quite happy.





Took it out for probably the last tuning session of the year. Moved to 26* timing under boost and was able to cleanly run it up to 5000rpm, about 80% duty cycle, so there's still some room, especially with my plans to add water over the winter, should be able to run 12:1 or 12.5:1 a/f under boost.


Back pressure testing

at 5-6psi
under 3500rpm back pressure stayed below 2:1
~4000rpm 3:1
~5000rpm 4:1

these turbos are very responsive on the street but the are definitely choking it up top. Seat of the pants rev time from 4-5000rpm is not that great. Maybe stage III wheels would be enough? Probably time to call a professional now that I have data....

[you NEED a Bov! thats why it popped when you went on/off the throttle, could very easy bend throttle blade in the TB, cool build!

Ya, in theory this build shouldn't have required one, lots of OEM systems at this level don't, but in practice this one does. At lower speed WOT to idle the engine completely falls apart like all the vacuum lines were blown off. I'll be adding the BOV this winter.

"should be able to run 12:1 or 12.5:1 a/f under boost."

I suggest running it no more than 12:1 a/f under boost.

Short, and with the car just in drive as I didn’t have a hand to shift and hold my phone :P Had to feather the throttle in the one of course which caused upshifts.
