Forced Induction's FI91X report!

Some progress.

Unless you plan to start using a tow vehicle at the track, I'd keep the radiator. You can set the mixture rich enough to keep the engine cool on methanol, but it quickens the oil contamination. The radiator can still prove to be useful with methanol. You just don't need as big a one.

Don that flange looks excellent...

Very beefy looking flange!

How do you plan to support the weight of the turbo? As I'm sure you know, it will cause stress cracks to your headers if you don't get the weight off of them.

I use a tripod frame that comes off the front of the engine and supports the turbocharger weight from above it. Very similar to how F1 used to do it. I couldn't find a clear picture of it to post. I'll try to remember to take a picture of it to post later.

The adapter is finished. I was alone at the shop so I couldn't hang the turbocharger on the car.

WIMP:biggrin:

Use the engine host!

That turbo can't weigh more than 90 lbs, should be a walk in the park to hang it :biggrin:

Oh, believe me, I tried to hang it, but I had to abort the mission before I lost all the strength in my arms and couldn't lift it back out of the engine bay.

I found a pic of the previous engine build with a good view of the hanger for the turbo.

LOL! Actually, that's a good idea.

Another view of the hanger.

Actually, I know a few people who have used a hoist when installing big turbos. Makes life much easier when making brackets.

Bent6. I just re-read your first post. Your reaching 15 psi in 2 seconds. The first time I read it I thought it was .2 seconds. If you need that 15 psi quicker, up that shot size.

With your large plenum, you should be able to make an internal port injection system easily. Hang the system and put the thru-walls on the plenum cover.

I've got to see what this turbo looks like on the car. I going to find someone to drag to the shop so I can hang this thing.

The turbo is mounted. It looks like everything was designed it. Maybe it was. It fits beautifully. Pics coming soon. Working on them now.

The finished adapter.

1st set.

2nd set.

Yep. Pretty sure I'm not going to have any exhaust back pressure issues.
Next steps are to modify the hanger to support the turbo at center weight, hang the boost control solenoids and hook up the oil lines.

Don, that beautiful man. Yeah the backpressure should not be an issue. If for some reason it does so, we have some other turbine wheels or housings....lol

That FI-91X that made 1481rwhp on the 2JZ, the backpressure was only 1.12 max and that is with the small Turbine housing.

Nice!! Plenty of room...
