I did not wrap my manifolds but I plan on doing so (or possibly having them coated) over the winter...if you can, I suggest a turbo blanket too. The pipes from the manifolds to turbo and turbo to down pipe are all wrapped with DEI. I only drove my car a month before i put it away for the winter and will be preparing to tear the motor apart again due to an extreme oil consumption issue (possibly installed the Gapless ring upside down). The underhood temps did seem to be very high, and my cooling system struggled to keep up. Granted, I did not melt anything as far as i know, but i did have an over heating problem on a 90 day here in Columbus. I have stock radiator pushed forward and aftermarket fans which may not even flow as much as the stock ones (i can't seem to find a sure answer to how many cfm stock fans flow).
Definately take any heat shielding measures possible.

 

I'm not talking about retarding 15 degrees from where its running. IE 40 degrees na and then pull 15 down to 25.

I am talking about firing after top dead center, no timing advance - actually firing with the exhaust valve open.

 

Ok, so did you get that fixed yet?

 

Keyed hub will be here tomorow,, if the ice clears lol

 

Understandable about the ICE!!! Here in KS we got LOTS of damn ice.

Hopefully that will fix your problem though!

 

I need to get that on there and then find a timing light. I like the crank trigger setup but I was shooting in the dark before.

 

Just for everyone's info, I took the parts to get coated yesterday, cost is $431 from this place http://www.hotshotusa.net/ They are literally 10 min from my house so it worked out well. I will post pics of the final product next week when it's done. Oh yea, they offer turbine housing coating, anyone done that before and have results?

 

Alot of people do turbine coatings... typically run $50-100 for the coating.

 

Yea, I'm thinking about doing it, makes sense if I coat the whole kit I might as well coat that too.

 

where's your hood latch???

 

I dont have one

 

Changed my mind, after doing some reading, it seems that a turbo blanket is MUCH better. Gonna save the money from coating and buy a blanket.

 

Cool. If you are interested, I have a black turbo blanket for sale (T60-T76 T4 turbos). Shoot me an email: jon@lt1boost.net

 

I got the new hub/pulley on. Its fricken cold and ice is still on the ground.

I started it for a minute. Idle was much better and I tweaked my tune back to 0 offset and a few things. Couldn't take the fumes so I am waiting for at least slightly better weather.

 

Its fricken snowing now.... but I did go out a drive a little. My tune was wayyy off from tyring to tune it with the timing so far out.

I spent about half and hour on it and have some good results.

Made 6-8# several times for short bursts, still adding fuel because its going lean on me.

Exhaust got quieter... firing with the valves shut ftw.
Runs much better, easier to tune.
The few dry spots of road I found where I could actually lay into it excited me just a little. This is my first time ever driving a turbo fbody and it is simply amazing. The smallish t70 comes on pretty much instantly. I can hold the throttle @ 20% and she makes boost by 3500. I haven't gone wot yet, but my boost runs where only 60-70% and I was seeing boost below 3k. Can't wait to go all out with it.

As far as temps nothing is melting now. Minutes after killing the car I can touch the wastegate and downpipe. 30 minutes later I could touch my manifolds. Thats better than my uncoated longtubes.
