Hi, I just saw this on Facebook. Anyone experience with that?

I think @RITDR had his done through him. Josh does really good work and is pretty well respected in the Ecotech community.

Yep. Super knowledgeable guy

For $300 20-30HP seems to be a bargain. Wish I hadn't just bought the Ls4 TB adapter. Oh well.

I have been meaning to send mine to him for the last year or so. One day I’ll do it.

I would ask to see Dyno results before that investment. While it will definitely increase throttle response, probably to an annoying point on a Goblin, it's hard to believe a 10% bump.

Either that or wait for the unicorn (TVS 1320) for a reasonable price to show up.

Steigmier used to be the go to for this type of work, but Cat V is highly recommended now. If a TVS1320 isn't in the cards, then having the M62 ported is a very good way to maximize the M62's full potential.

I’m after lower iat, more than power.

What have you done so far to lower it and what do you expect to gain? I have the dual pass intercooler manifold, the phenolic spacer, and E85. Knock is no problem anymore. I was thinking about the water injection... But I really want the TVS, but all prices are just insane! I rather port another more reasonable priced supercharger over.

Not much, but have things on my work bench to help. I don’t really have problems until autocross from June to Oct when it’s 100 outside. Only get a couple of runs in until it limits my boost and such. I need to get cooler air to the filter, then I have some radiators I want to add. It’s just been a back burner thing. Making the charger more efficiest will help a lot. I’m not doing e85, because it’s hard to find in my parts and don’t want to be reliant on it. doing the charger port thing is more for my full engine rebuild, but want to have it done before all that to work out kinks.

I got that from a facebook group. It also seems like this Al McClure had that done too. I think that's the guy from ZZP and moved to OTTP
