What a weapon!
Keen to see some drag runs on it.
-
Here is a dyno run low boost ( 200kPa). Dyno was maxed out at 1000whp @ 5600rpm. Tuner studio indicates 1340 Net HP @ 6800rpm on the street. 100 to 200 kph in just over 3sec. Ready for hi boost now.

Here is a video of my previous 355ci in Bernardo's Camaro. We ended at 29° advance @ 270kPa
He used his old Banks kit on my long block. . Banks guss exhausts also seem restrictive. We are now waiting for bb turbos and 4into 1 collectors.

Alex. I think I have seen similar issues to the Injector drivers not working. I did a small mod to a BIN file and uploaded it, and the engine started running like crap. I tried a couple things and it was late in the eve so I quit. I came back the next day and started the motor again and let it run for 5 secs and shut it off. I had 4 warm pipes and 4 cold pipes. When I wrote down the cylinders to see the pattern, the first 4 cyl in the SBC firing order where warm, the last four where cold. Don't know if it was the waste packs or the injectors. I got an older BIN file and did mods on it and uploaded it to the Tec3r and it fired up and idled on all 8 cylinders. I had this happen a long time ago and thought it was a waste pack, so I bought a new one and installed it and had he same issues, in that case again I had to make a change to the BIN file and save it and upload it again to fix. It seems that the S19 files gets corrupted some how so uploading it does not address the issue, you have to change something and resave the BIN so it builds a NEW S19 file..... Just my guess..... Next engine I'm probably going to FuelTech since I'm building mostly drag cars for my own use anyway and the FuelTech gives the user major support for drag and turbo, but you have to be your own tuner...

Alex,
Thanks for the update. Are you logging your updates to your project somewhere where I could follow. I enjoy reading and following boosted projects.
Best of luck,
Michael

Hi Michael,
I Turned to an MS3 Pro ECU to replace my TEC3R. I had too many troubles with the TEC. Injector drivers not running, auto tune not running etc..
The MS3 is very good for what I do.
I have to look for my .dat files. If I still have them I will send them to you.

Hi Alex,
This is an old thread, but hoping you still monitor your account.
I have a SBC 355 Twin Turbo as well. I am getting ready to switch over to E85. I have replaced my injectors, fuel pump, fuel lines and rewired for Sequential Injectors. I am also running an older Electromotive TEC3r that only support WinTec 3.5.6, not 4.x. I see you where running 4.x. I may send in my TEC3r at some point to be updated with more memory to support the new 4.x DAT files.
Is there any chance I can get you to send me your last .DAT file that I can look at with WinTec 4.x and compare to my 3.x file configed for GAS and see where I need to adjust Vol. Eff., Timing, etc.
Thanks
Michael

I had to stop tuning and placed an order for a set of ID 2600cc. My 2200cc Bosch injectors went wrong after 6 months of E85.
This is what I have (fuel pressure test 30 PSI fully open). This week end I will perform a real test with pulses at my 60PSI car fuel pressure.
-
Nice, post some results and pictures when its possible.
-
First test drive is promissing. We went 5800rpm at 170kPa and already have 70% duty on the 2200cc injectors. This baby is breathing deep.

Hope I can start tomorrow.
SCS is a pinion super heavy duty transfer case with optional front disconnect
-
Nice runners and flange, plenum is going to be billet also? What its a man scs transfer ? perhaps a heavy duty machinary transmission?
It s going to be very interesting setup to watch it work .
-
We are now machining the flange with runners. Will be finished tomorrow. Then I will assemble the plenum. Engine has already been started. The primal cry is promissing :)
-
I am waiting for man SCS tranfer case with front disconnect as the NP149 will never hold behind this engine.
I also build a CNC intake manifold
-
Nice headers, it looks like in little time is ready for brake in and dyno.
I think you better look for a awd hub dyno for the near 1600-1800 hp of your engine .
-
I am almost ready to put it back in the car.

Nice Chevelle , interesting transmission setup . There is a drag Corvette in Poland with a similar transmission setup that goes high sevens
on the quarter "VTG Corvette" also they do a some others awd V8 . I always curious what transmission package , front differentials,
transfers and gearbox is apt to resist a high hp V8 turbo engine , once I looked a build that uses awd transmission of an off road
truck , maybe thats what all those setup are with some modifications ?
Attached are some pictures of my father 67 Chevelle with a stock 350 c.i engine 240 hp going to install a hot cam, headers and
maybe if time is friendly a little head work .

Here are some
2WD
Compared to a Bugatti Veyron Tyre
And finaly 4WD

Keep it posting that powerful build ! post a picture of the car.

According to RFD the heads flow 410cfm, I measured them at just over 400cfm@0.750" on my flow Bench.
The valvetrain should do the job with T&D rocker shaft , 7/16 tappered pushrods, the springs at 300+ Lbs seat and 700+ lbs open pressure with Titanium valves (intake).
Those 2.20" valve weight 81g, compared to 128g for the 2.08" I had previoulsy in my Vic Jr heads. I start the build saturday, I will post pictures of those parts.

Cylinder head air flow and turbos are capable for your HP goal, 1800 hp .
To make those cylinder heads flow around 380-400 cfm a 427 c.i engine have to spin around 8400 rpm and open the valves large quantities,
not an easy task on the engine building part of the proyect .
a 427 c.i @ 8400-8500 rpm and 25 psi of boost with your cylinder heads and the right components (camshaft, valve train, rotating assembly,etc)
could achive 1800 hp, but I think only a race car could manage all that power . Technically speaking since it is a street/strip car a little smaller
cylinder heads and turbos could be more usable , I am not saying that you are going to feel lag of torque and power on the low and mid rpm ranges ,
its impossible to feel insufficcient torque and power with that engine size ... as I say my comment is technically speaking .
Nice proyect to enjoy building and fun to test .
It could be interesting to see the cylinder heads flow/lift charts if you have it .
-
I will go to the dyno, track and highway.Would like to see some mid 8' . But this is mainly a street application
Turbos are PT7675 with the 0.96 turbine
-
Nice fabrications, this proyect is going to see track testing or is highway porpose only ? which turbos are you going to use ?
Definitely an interesting proyect , I am following time back...
-
I just finished intake and exhaust manifolds. The final engine assembly will start soon.
-
I just watched the Webinar concerning the head gaskets and wonder witch type to install. I used to run the FelPro Loc Wire composite gasket at 25+ PSI.
I concider now the Cometic MLS, but would those hold for 2000hp ? I am not sure I want to install copper gaskets, coolant sealing may by borderline in winter with cold start.
That's my last big question about the setup.
