I like the re-tapping the manifold much more then the spacer. Hopefully the cheap studs that you cut short hold up, that is the only possible thing I see possibly going wrong.

As for which T3 China Charger to go with below are the specs. Basically you want to search eBay for "t3 turbo 2.5" v-band .42ar" and then compare the specs in the auction to what I have below. Get the one that matches these specs exactly. CXRacing and Rev9Power are the 2 brands that I recommend and you can usually make an offer in the $190-210 range and have it be accepted. The big thing you want to make sure you do is port the waste gate hole to be larger.

T3 TURBO CHARGER INTERNAL WASTEGATE .48ar
Intake: 2.5 inch
Inlet: 2.25 inch
Compressor trim: .42ar
Compressor Wheel diameter: 43.20 / 60.41
Turbine Wheel diameter: 45.74 / 62.86
Exhaust Trim: .48ar
Turbine flange type: t3 flange
Down pipe flange type :2.50" v band
Cooling type: oil cool only
Horsepower rating: 325-350
Actuator setting: 8psi

Thanks for that good info. I'm going to throw it into the description on the video. Not surprised on the wastegate either, with the Begi churbo on my other car I could lock the flapper open and it would still hit 9psi by redline, lol. The Garrett barely hit 1psi when my wastegate bracket broke.

The begi churbo is a joke and should be outlawed.

I know first hand, but............. I already have one so I'm using it. But yeah it makes like 3psi @ 3000 with a 2.5" catless exhaust. When I dyno the car post turbo I'll be strongly recommending against it and have a graph to show why, lol.

In the 'I Want Your Spool Data' thread I have this churbo vs my 2554R (in the last couple pages of the thread somewhere) if you were intersted. On this car with stock exhaust I'm going to post it up again just to make everyone else feel better about their setup

Oh no, I never actually installed the adapter on a car, just bolted the setup together. On my other car I've always just had the Begi cast mani.

Not sure how soon I'll be able to make it up to California Speedway but I really want to find out for myself as well. I'm thinking about marking out a rouge quarter mile on a desolate road and running it, combining on board video with MS logs to calculate my speed & time.

I though that might have been what you had, the welded compressor inlet screamed BEGi touched it.

You mentioned posting 1/4 trap speeds to see how legit my 276whp dyno reading was, which has had me wanting to run a quarter ever since. The nearest one is pretty far away, but I did a couple other tests that should be somewhat informative. So my best 1/8 mile has been 8.558@87.88mph. Using GPS and MS tach readings, I did a couple flat freeway pulls simulating the big end of the quarter (80-120mph) and estimating the car should run 12.5-13.0 I calculated approximately 112-114mph trap speeds. (Timing from 87.88mph up to 4 and 4.5 seconds of acceleration past that, simulating 12.5 and 13.0 ET's.)

Also, I have run three different stock 2015 Mustang 5.0's in the 1/8, and I trap 2-3mph higher than all of them. Those cars usually trap ~112mph in the 1/4, so assuming I would hang with them or pull slightly, that confirms my 112-114 estimate. What thinks the mt.net skeptics?

Edit: weight with driver: 2400lbs

I think the bench racing is cute, and as always, oh so optimistic.
The track has a tendency of being the biggest skeptic, and usually very humbling to people who use calculators to estimate how fast their car is.

If you truly run 12.5 @ 114 with 276 I will be very impressed and will prop cat every one of your posts in this thread.
*edit: I'll even apologize for doubting you.

just for fun, here's a calculator:

I'll be in Santa Cruz tomorrow, want to race my slow 15 mustang?

Well, I was relying more on actually trapping 2-3mph faster in the 1/8 than a car known to trap 112 in a quarter. I'm not concerned with ET as it has more to do with how much you dislike your trans.

Even if you hated your trans, it's hard to get these cars out of the hole unless you got some really soft sticky slicks.
But who cares about et, I'm more curious about what your trap speed will be. 87mph in teh 1.8 is legit though, grats on that (if that's what you ran)
my MSM trapped 84 in the 1/8 and 105 in the 1/4, to compare against something. (with 230hp,j at least 200lb more weight and 6sp gearing)
