First attempt with twins--failure

[hdm48]

Well, the first attempt with the twin turbo's failed. But the polished stainless steel headers look great.

I'm keeping the headers for the second round.

After spending 16 hours fitting and re-fitting everything I took it for a drive. The twins sound like nothing you've ever heard before. Kinda like a F-15 spooling up for take-off.

The only problem was, I could only get 5 lbs of boost. Then, after some more checking, I found the front turbo had lost an internal seal and was dumping oil fast. I made a call to the turbo GURU's and was informed the pitch angle and housings were not diesel suited and my exhaust pressure and heat blew the seal out. (anyone know where I can get two hx35's?)

I figured that sence I was there I opened up my stock exhaust manifold and turbo to flow more and picked up 2 more pounds of boost.

So, this was attempt 1. Now on to attempt 2.

Got any pic's.



Even if they didn't work. The pic's would be nice. I bet you were dissapointed. I know I would have been. But when you are in uncharted waters you never know what will jump up and bite you.

I have a request... .

If y'all don't mind, I'd really like to see further discussion of this project on this thread, or in the 1st gen forum. I've been following Mark Kendrick's "twins rock" threads and it is very exciting and informative. However, seeing how these things apply to the 1st gens would be great. Oo.



Thanks,

Sean

I talked to Dave and he is going about it from the other way. He's doing parallel and I did it in series.



I'll interested to see how it works. I don't see the benefit of a parallel turbo setup on an ISB. But inovators are not to be ridiculed. I'd like to see it work. More options for power is always better.



I think that a Hy-9 /(hx40 or h2e) would rock on a sequential setup for sub 400hp trucks.



The 1st gen lacks fuel enough to properly spool a bht3b. . I'd still like to see it to see if I'm right.



If anyone wants to try an H2E uses the T04 flange... HX35s use a T03 flange

Any more progress on this? Details, pics would be great.

What about Turbonetics turbos? I think that they are garret based, but they offer ball bearing innards and even ceramic ones at that. I was just wondering, when you think about it, ceramic ball bearing turbos make our "bushing" bearing turbos look like covered wagons in rush hour.
