350 hp?

What all have you had done to your car?

The service advisor at the dealership I got my car told me today that his buddy is running 525hp at the wheels in his BRZ. All it took was an LS3 and related bits swap

random guy has a buddy with a 500hp car, wait I've heard this one...

I have 498whp, how deep are your pockets........?

- Scratch made exhaust manifold
- Scratch made 3" downpipe and section leading to 2.75" J2 exhaust (when they were under $400 shipped on eBay over a year ago - when I'm not lazy I will be making a full 3" all the way back to, hopefully, dual tipped mufflars). No cats.
- Billet, ball bearing PTE5558
- 3" compressor inlet/intake pipe
- 2.5" intercooler piping from the turbo all the way to the intake (well, up to where the cold pipe goes to 3") with stock washer tank and all the stuff other kits replaced when turboing these cars was a new idea
- Rather large intercooler (everything was purchased with the idea of running 450rwhp, so it's a bit overkill for only 360)
- ECUTek
- ID1000 port injectors
- Deatschwerks DW65c pump (to my surprise it hasn't failed)
- TiAL MV-S wastegate
- Tial BOV
- Our spec'ed ClutchMaster clutch and their off the shelf light-weight flywheel
- E85. My pump map is basically a limp-mode map to get me to an E85 station and that's it. Don't know, nor care, what the power is on pump gas.
- Full boost is curbed at 11psi until I get a minute to put it back on the dyno and retune it to a nice round 400rwhp, whatever boost that may be (there's a good bit of meat left on the bone timing-wise too)




-Dyno is same car (bone stock vs current setup/tune), same dyno, same driver, different day.
-Was our first crack at tuning a twin, and the first time ever with an ECUTek, so I know full well it's a "crap" curve compared to the more experienced players nowadays - we now have a much more firm grasp on the platform (note: I am NOT, in any way, promoting a business, services, or any remotely-related-to-vendor things - we are an MR2 shop)
-You can clearly see there is plenty of power left to be made by how it never levels out or drops off. Like I said before, we bought everything planning for 450rwhp, but were given false info once we were at the tuning stage, so we went ultra conservative on the tune. Now that we know ~400rwhp is considered "safe" enough on stock internals, I will turn the wick up when I get a minute.
-Blackstone oil analysis at 6500 miles (~8400 on car now) was perfect, and that was after about 6000 miles of being at this power level.
-Setup was designed to be 100% removable, so nothing was cut or otherwise permanently modified to fit anything.
-I still average ~24mpg on E85 (highway, ~22mpg mixed) with a good amount of boosting (via calibrated mpg gauge and doing the maths).
-Desperately needs brakes, especially after our group MR2 run in the mountains of Kerrville a couple weekends ago.


At this power level the car is just plain fun. It's not a monster, a killer highway roll racer, or anything to "fear" on the track or streets. It drives like a 100% stock car. Just a tad quicker. So if you expect something else with your 350hp goal, you will probably be disappointed.

You should buy quality parts regardless of power levels, so that's a moot point.

You should also get a quality tune regardless of power level, so another moot point.

Closest E85 station to me is 20 miles away. I get ~240 miles per tank with E85 and a fair amount of boost usage per tank. After calibrating the mpg indicator for E85, it says an average of 22.3 right now. Doing the maths (usually fill around 11 gallons at 240 gallons), I get an average of 21.8 mpg. I'll see 24.x mpg average on the highway sections. I live in the "country" near DFW and I can get to Dallas, Ft Worth, San Antonio, Kerrville, etc using just E85 with little to no worries. Plus, if you're even remotely intelligent -and by this I mean just smart enough to listen to your tuner- you will have a map for a pump/E85 mix, and a map for pure pump gas for the times you get stuck out somewhere without E85 (if you go anywhere with that being a possibilty).

.

Well shit that's my car! And I can confirm no need for internals to hit 350, just good quality parts, E85 and a good tuner.

Too bad we didn't get a chance to meet Rob I was looking forward to it!

Yeah, I was bummed when Aaron said you were picking up (and dropping off) the car on a day I was at class. How'd you like the Shiteos loaner car? haha FWIW, your results pretty much gave me the motivation I was looking for to turn mine up to 400rwhp. Your torque curve is actually what I'd like, but that's splitting hairs.

Oh, on another dyno -even another dynojet- you should be making over 400rwhp. Our dyno reads a few hp lower than other locals'. And by "a few" I mean literally 3 or 4 hp. So you can technically claim 400rwhp with a good amount of confidence if you so desire.
