Sub. I'v been wondering if he was still selling turbo kits. Did you ever get ahold of him?

His messaging service doesn’t work sometimes, if you call him he will get back to you when he isn’t working.

I just wanted to update this post. Yes I did get in contact with Brian. I purchased a twin turbo hot side from him. He was great to work with and I did get my order. I did take longer than expected, but it was worth the wait. I am still putting my new combo together so I did not run it yet. I will update when I finally get it running. He is an honest guy. I would not hesitate to do business with him again.

Thanks for the update. Good to know. Trying to decide if i wanna go turbo or supercharger. How long was it from order to getting the kit. So your going from a single to a twin kit? how come.

I ran both superchargers and turbos. I don't think I would ever go back to supercharger, JMO.

As far as time frame, I would contact Brian for an estimate. I know he is really busy. Right after I ordered my kit he stopped taking orders for a while to catch up.

Why did I switch from a single to a twin? Really??? LOL More power of course!!! The single turbo was choking my engine, way to much exhaust back pressure. The twins will help with that. IMO opinion easier to fit 2 small turbos over one large.

Brian builds good stuff. I use headers from Brian, but I bought them with uncut unfinished collectors.

I made my own flange area and cross over.

I run a single Forced Inductions T4 flange with 1.25 AR and a 4" exit.

My car is 3200lbs and I nominally run the 1/8th right at 5 flats, sometimes high 4's, in the 140's even with exhaust to the back axle.

I'm just out of airflow to optimize the engine. I'm at 25-26 psi boost and really need around 30 psi.

I'm thinking of a custom V band flange turbo on the B&G headers, which should get me another 5 pounds easy with the same setup.

What turbo you running now. I have a 363 also. Hellion was telling me there kit and a 7675 would get me my goal of 750rwhp.

I'm not a big fan of the Hellion kit. I would look else where IMO.

I was running a GTS 76. Made 787rwhp at 15psi running e85 and a lot of meth through full exhaust and a AOD when my injectors ran out on my 352. Pretty healthy motor. Back pressure was over 2:1 which is far from optimal. Was 35psi in headers. The newer gen 2 7675 is good for more. You are going to have higher back pressure than I was running. Problem was getting a better following turbo to fit on the street kits, that's why I went with twins.

Precision sells the stainless v band housings for the turbos I just bought. They are pricey. I didn't want to try them and find out they were too big for me to spool. If my. 96 housings spool I might think about buying them.

Do you think the v band housing will give you another 5psi? Will your turbo flow any more air at the higher boost? Just curious. You are definitely making power now.

I have an 88 billet wheel with a 91-100 turbine in a 1.25 AR ported out housing I'm pulling off. It was a good match to my old engine and worked well for a cheap turbo, but I lost boost with my new engine because the heads are way better. My base NA horsepower on a Superflow dyno is 10-15% higher everywhere from 2500 RPM up to red line.

I only know what multiple turbo people have told me. I'm going to get more data logs when I get rolling again, my axles and gear set have gone past life limits and aren't safe.

Jose at Forced Inductions and a guy at Bullseye have both said the housing choices with the V band will let me optimize the system better. Of course Bullseye says their turbo will out spool and out run the FI turbo, but Jose has a great reputation. I have no history with anyone but Precision and Jose at FI and I'm reluctant to spend $4000 as an experiment. Jose is $1000 less but is also a bit slow delivering.

I run about a 2:1 or slightly less pressure ratio.

The Dashed lines are after the engine change. The boost is less but the MPH higher. You can see the boost tail off, which tells me it is probably running out of compressor airflow. That makes sense to me if the engine flows better.

Interesting. I will be following your updates.

Brian told me I should be 1:125ish on back pressure. I'm running 64/66 gen 2 turbos with. 96 housing. I'm going to datalog to see where it is. Should be a big jump in power just from the drop in back pressure. I would be happy at 1:1.5. Looking to make power up to 7200-7500rpm with new cam and stronger springs. Figured new setup should make 1500fwhp if I ever turned it up. I just have to remember this is a small tire street car lol. Probably set it to 1000-1200 hp. See what happens.

Going to twins from my single GTS 76mm kit was the BEST thing I've every done. This was at around 19 psi and not much timing...car is heavy also...3400 + lbs.
