Crawford power blocks install and first test.

glad to see your enjoying the BPB


I will hopefully be putting these on my car soon! I like to hear that it helps mellow out that ditch in the torque curve.

Do you have any plans to dyno your car? either before or after you get the OFT?

@mid_life_crisis as the blocks change the VE into the engine, having a freer flowing intake won't really make much difference. Also, the stock intake isn't much of a restriction anyway.
@Corradooo the car will idle differently for the 1st 30/40 seconds after a reset, that always happens as the ECU recalibrates and adjusts the cams.

I just went for a quick spin and took my first passenger along for a ride. Her response "it feels different! Faster earlier, and MUCH smoother. The power doesn't just kick in, it's always there."

I def agree. I was shifting anywhere from 3k-redline to get a feel for it and even when just cruising, there's still power when you hit the pedal. I slid a few turns and flipped a couple of sideways uturns and the car kept the wheels spinning longer with the throttle pressed less in and less of a need to slam it giving me a longer range to continue the power making a smoother transition. Power pretty much everywhere. These things are really awesome

Hopefully in a few weeks I'll dyno as is, then with OFT on pump, then with OFT on e85

Should allow more flexibility at the track. If you have to stay in gear longer for a corner, you have more revs to work with.

If you want to be as fast as possible, it is better to redline it even with the significant power falloff. Especially from 1st to 2nd and 2nd to 3rd you have much more power at 7500 rpm than at the rpm after the shift - even with the BPBs installed.

So what exactly do those gears do? Lengthen the 1st and 2nd gears? What effect does that have on 0-60 or top end?

Shortens your 1st and 2nd, I'd imagine.

Probably only affects top speed in 1st and 2nd gear. If you look at the graph they posted, you should top out in those gears sooner. But it'll keep you in the meat of the powerband.

Not sure if it's related, but I always noticed that the shift timing from 1-2, 2-3, and 3-4 vary. My friends said the same thing about their twins. The 1+2 gear swap will probably improve low end acceleration, and top speed won't be affected unless you change the final drive.

about to purchase these.thx for info OP

Yes, they reduce the rpm drop from 1st to 2nd and 2nd to 3rd.
This especially sensible with their shorter final drive (otherwise 1st and 2nd would be very short).

But this is not the point I wanted to make. I just wanted to show a graph which shows the rpm drop when you shift (stock gearing). And when you look at the power graph you see at what power you are when you shift at a certain rpm and drop to a certain rpm. (And you'll notice that you have more power at 7500 rpm than after the shift, despite the significant fall off.)

[Corradooo]

Gotcha. I could only see the second pic, the first wasn't displaying. I still shift at redline to get me higher in the midrange through each gear after shifting when really pushing the car anyway, but when cruising or just going around town I shift much much lower, and the blocks still give me a feeling of power with much less TQ dip than before. It feels great.

With all the parts you have on the car and BPB, if you had a tune with our dedicated map for the bpb you will notice a great overall improvement in performance.



Cheers.

Having another set or 2 of hands would def make it go fast but isn't needed. I can stake some pics of them installed in a little bit. I didn't put the fuel rail covers back on yet, they were kind of annoying, but not too bad.

Upon first start I noticed the cold start revved a bit higher for a bit longer than normal, then tried to drop a bit, but came back up, I probably should've disconnected the battery to reset the ECU to try and re pickup the BPBs. Will do this later as well.

First drive drove about 10 miles, with a huge smile the entire time. This is how the car should feel. Getting on the gas between 3k and 4.5k used to do absolutely nothing, now the car actually pulls through in the lower range. Power feels instant and smooth until I hit about 5k where it REALLY jumps up in peak, and the drop off in the top end is barely noticeable. At one time I looked down and was at 80mph in 3rd gear not even at redline yet.

Only drove to a meet, then right back, was already dark and late, didn't want to bring attention and not be able to easily see sneaky cops, so didn't really get on it too much yet. Will def give an update after a little more time in it today, but I would already def suggest this to anyone who is either staying NA or not doing FI for a while.

My car is running perrin CAI and inlet tube, GFB pulley kit, borla UEL headers, ARK catless test pipe, perrin overpipe, berk dual exite muffler delete and new wheels and tires, and now the BPBs.

Before the addition of the BPBs, there was a night and day difference driving my car over my roommates stock BRZ. Now there is a noticeable difference between my car before and after the addition of the BPBs, so my car compared to the stock is like a whole new car now. Couldn't be happier!

Really wish I could pick one up now, been looking into it for a while and I def think it's time, but just lost my job last week, don't start my new job till the 16, and probably won't get a first check for a couple weeks, so hopefully I can have one in a few weeks. I plan on doing some reviews with the different tunes and I also have a stock BRZ to compare everything to. I really can't wait. Wish I could have the OFT right now! Lol

No problem. You got priorities to take care of first. We will still be here to assist you when you are ready.

The OFT will be a great compliment to the mods you already have. Since you have a stock BRZ to compare it to. Once you get the tablet installed on your car you should be able to get a good idea on how it compares to stock.

So I was wondering if tuning is mandatory with the BPB, or if a these can still be beneficial without a tune.

Obviously the tune should extract the full potential of these, but will they still add AUC without the tune?
