but bryan still answers his phone, so you should call him if you have any questions that us forum members can't answer

 

thank you Node

 

Your welcome

 

You can call Bryan directly also. Do a search for "BNR".

 

Hey Cosmo.

If you have any questions about your turbos, let me know and I will do what I can to answer your questions...

Bryan,

Your fix for the boost problem worked like a champ. Question is, do you happen to make an improved Wastegate actuator?

And what was JRAT's boost problem?

 

His foot wasn't heavy enough for the accelerator!

 

Slow spool, inability to make more then 13 pounds of fun. Turns out the wastegate actuators on the turbos are weak, and cant handle the added pressure of controlling one of Bryans Hybrids.

He recommends redrilling the wastegate control arm hole (at the turbo) a bit farther back. I did this, and it turned that turbo into a friggin mad man!

My thing is, I dont particularly like to rig up something, I would rather have an improved wastegate actuator.

 

Haha

Thumbs up to BNR good stuff.

ok interesting. can you elaborate alittle more on what you had to do j-rat? When I get my bnr stage III operational or my car operational rather, then if I end up having this problem I wouldn't mind knowing exactly what I have to do to fix it. Oh damn I really hope it doesn't have this problem. I'm thinking, no joke, I've removed and replaced the turbo about 7 or 8 times in the past couple of months

 

you shouldnt have to pull the turbo to remove the wg rod and drill a hole in it.

 

You win t3h pr1z3!!!

Yes, you do NOT have to remove your turbo to access the wastegate actuator. This job was done in about 15 mins tops.. Easy cheesy.

All you do is remove the actuator. Redrill a hole in the actuator arm where the actuator attaches to the turbo, a bit closer to the actuator itself, and reinstall. This increases the pre-load on the spring.

From what I gathered from Bryan, he has already figured out this problem, and for those that buy one of his turbos now, the actuator arm comes with a turnbuckle so you can adjust your pre-load.

I am here to tell you now, this mod gives you an incredible increase in spool, and near rock solid boost control.

 

ok so since I"m slow I drew a little diagram to make sure this is what you are talking about.

 

hmmm, been having some issues trying to control boost with my modded turbo also, wonder if pulling more tension on the spring will help cure my problem also.

 

What are the symptoms?

 

just seems a little sluggish and a tiny bit erratic at times, since it is the stock spring tension i was thinking it might be pushing past the wastegate somewhat.

 

That could very well be!

 

would anyone have any pics of this?

 

SUMBITCH........ I've been wodering why i can't seem to get much more than 14 PSI out of my BNR stage III .... but, in reality, 14 PSI is pretty damn impressive so i never gave it much thought.. I'm gonna try this tonight when i get home!!!!!!

 

not to thread jack, but couldnt you shim (fancy word for add washers) the wastegate actuator back bit...oh say 1/8 or 1/4 in and do the say short of haveing to "rig" your actuator?

 

how many bolts is the wastegate actuator held on by? I've got the one bolt I could see out but then I tried to take it out and it's still hung up on something. Any help would be great! Thanks.

2 bolts about 1.5 inches from each other.
