Trying to figure out a few things for dignosis

what should a 55k car with the following mods be at, in terms of boost

• LT headers with race cats (FLoor fab)
• MB 82mm TB
• 168mm Evo puley
• Evo cooling kit

Thanks

I have a 185mm pulley and shorties and hit about 15.4 PSI max on my OBDII logger.

remember with longtube you dont have much restriction on the exhaust side so you will loose some boost. if you cant find a leak then i think it may be time to upgrade to a bigger pulley.

i have a guess on were to look for the leak...might be the spacers between sc & surge tanks. Will let you know when i do. Thanks for your help mate

just wanted a ruff figure on where i should be in terms of boost, as i logged it with my old set up, but never with my new one

I have the same set up with 180mm pulley and I only get 12 psi in third gear. I do have long tube and 3" mid pipes if that matter.
