Speedster 200 Build

[tiderider]

I don't think your 2006 Siemens ECUs can be tuned for the VT1100 fuel injectors. I believe only 60s or 80 would be possible. Unless your adding new ECUs?

Hi Tierider i downloaded a map yesterday and the VT1100 worked fine, i give you all a update when the other engine is done and take it for testing

very cool, i may have missed it but whats the purpose of the billet exhaust manifolds?

[Speedster 800]

Had them made to accommodate the O2 sensors, also to test if any difference with the one inch ones. There was plenty of room so why not. they might act as a massive heat sink but will monitor the temps and post results.

First test run, 75mph, now to start adjusting maps and pumps. Play it safe at 8200 -8300 still got another 500 left.

What impellers are you using?

[Speedster 800]

Im using 13/18 three blade,once iv tuned it im going to try 4 blade 15/22. Had some issues with the TOPs valves, ill post GPS once its tuned and in full trim.

hey, how was long time results of rectifiers installed like that on the picture, without air cooling? no malfuncion?

Getting close now

[Speedster 800]

The rectifiers installed like that have had no problems, the bracket acts as a additional heat sink. With the air intakes there as well there is quite alot of air flow which was surprising.
Currently i'm just fitting 300 fizzle coolers in and when the weather is good will have some GPS speeds and vidios to up load.

I'd like to revive this thread because I bought a 2006 Speedster 200 310hp and am interested in building the motors for turbos and possibly that adjustable jet trim I saw in another thread. It would be wild to have a 70 mph jet down here in Miami. Is there any guru that might handle a project like this for me?

I’ll 2nd the revival effort. Still own the boat? Still running strong? Would love to hear and see what else you’ve done to it, what’s worked and what hasn’t with the pumps as well.
