[MikeyPee]

Just when I wanna give up on the GT350 mani, I see stuff like this

...get the gt350 throttle body installed in a couple weeks and see what it adds, been told by several 8-10rwhp

I'd like to see results of this! Stock TB vs GT350 TB. Lund told me there's no power gain from stock to gt350.

Nice work OP.
I don't have all the details of my gt350 setup as my shop is waiting to do a full write up release. I went from 438 to 456. I was 404tq and now I'm at 394 I think. This is in sae 5.
I have full ARH exhaust with jlt and gt350 tb. The huge gains were after 6700ish of 50-70whp to 7500 where it started to fall off. This was all on 93 gas. Shop said with e85 and tires I should be into the 10s.

Woo hoo. Thanks brotha! Hopefully I can get in a few months

They are $970 with TB on eBay. Always on there for that price.

I keep going back and forth on this. I just don't know if it's worth it for me. My car is a DD so I figure I'd be better off with just a tune. I don't drag often, but love the idea of the IM. OPG and TG necessary with this?

With a good tune to get the surge out this intake is possibly the best for a dd/fun car.

It's what I've been thinking, but I read that the GT350 CAI is placed right under the heat extractors. I fear hydrolocking the motor from being caught in a down pour. My car sees all weather.

Would be better if I could keep my Roush CAI as I would hate to have to buy another CAI. Damn decisions.

You run the risk of opg failing so while in there you might as well do the tg. The damper upgrade should really be done too. If you arent going to really use the increased rpm potential its a waste of money. It needs 7800-8000. Going to 7500 is a waste. You can already go to 7200 on the stocker.

Yeah and with mostly street driving, that high of RPM isn't going to be obtained much. Didn't really want to do the OPG/TG upgrades either. My wife thanks you for keeping my wallet lighter lol. I may just grab a tune and call it a day,

Get a flex fuel tune. That will be your best mod if you have access to e85.

I'm not sure about the gt350 cold air intake but my jlt just needed a 4inch to 4in coupler and it fits perfect.

Yeah regular JLT intake works fine just need a 4in to 4in. A gt350 intake isnt needed

Imho, it's completely worth it! Decent $ to hp ratio and you can always add a turbo or centrifugal to it.

my thoughts exactly!!!
