i do not like compare them but we should not leave negative effect about a company that we never used their kit.

The FA20 is not a traditional Subaru EJ motor. I can almost guarantee that LJ @FullBlown has spent more time dyno tuning FA20s than Crawford has.

bmw torque start from 1500 and ft86 start from 5500.
i prefer using a turbo that it's nature is like stock engine nature.
EFR7163 with full-race kit is my choice.
you see i do not prefer crawford kit fot it's top end and i do not like change internal for turbo.
crawford option is not my choice but i think we should regard professionals.
Mr.Crawford is really a professional tuner.

I think you made a good decision. The Full-Race kit is a great option for those looking to run a BW turbo. The third party reviews of Mr. Crawford's own car say that while he might be a "professional" tuner, he obviously hasn't figured out the tuning of the port/direct injection system on the FA20.

I regard Full Blown but i have no experience with them, maybe they put more time and found better result, i do not know.
i just saw their website , i think it's design could be so better
about crawford we know their effort was more on mechanics and maybe less on ecu tunning, i'm not sure but i just want to say in forums we should regard professional people like crawford.

be happy

Their website does leave something to be desired, but if you are interested, then I would recommend a phone call to Full Blown and ask to speak to LJ.

3. It's quite easy to make another kit scroll at low rpm. Put a smaller turbo on. Then you get a power band like Crawford, but you run into reliability problems. Then you build the engine. Then you tune. You still probably paid less then Crawford charges.

4. WHP is a better measure of actual performance because driveline loss is factored in. Crank horsepower is a bigger number, so it sounds better - good for marketing. Yes, dynos are different, which is why an intelligent person compares the same car pre and post mod on the same dyno with the same settings in as close to the same conditions as possible. Myself, I don't care about the dynos, whp, or SAE HP. I like my butt dyno and fun.

3. It seems to me that the Crawford (twinscroll) kit is the only US kit (except for the low hp AVO kit) that makes more than 400hp on pump gas AND has a reasonable power band (i.e. it makes significant power below 4k rpm). I do not want a turbo kit that makes power/boost at 4.5+ rpm. This is what quarter mile kiddies need. This is how turbos performed in the 80s. I do not understand why most people seem to be content with the lag of the turbo kits that are mostly discussed in this forum.

4. I also do not understand why people insist on comparing whp figures. Noone does this in Europe. No car manufacturer quotes whp figures. The reason is simple. Each dyno reads differently. Moreover, the same dyno reads differently depending on the exact configuration. That's why dynos are usually calibrated so that you can correctly convert non-comparable whp figures and quote "normal", OEM-like crank hp figures that can be easily compared. Do you believe that every tuner cheats and, therefore, insist on whp figures?

3. Agreed. That's what I am doing. For sure I do not want a laggy monster turbo that suddenly produces so much torque that the car becomes completely undriveable on a twisted mountain road. A flat torque curve is ideal. Yes, you sacrifice top-end power. But there is a reason why car manufacturers do not use turbos well-suited for quarter mile racing ...

4. My guesstimate is that 90% here in the forum compare whp figures from different cars and dynos. Most people do not explain how the dyno was configured (4wd, 2wd, etc etc.) although the configuration can result in HUGE hp differences. We are talking about more than 50hp. I leave it up to you to further comment on the intelligence of those people ...

That's the issue with the Crawford kit is that it doesn't have a flat torque curve. It kind of burps down low to make the car feel fat then it falls on its face

[Dipstik-sportech]

Hmmmmm bovs are a marketing ploy now..... Well if there was any doubt to the lack of intelligence on his part.

[Tiz]

I understand that they are talking about racecars only. Anyway, I think we should stop posting negative things about them.

My twinscroll tune is now finalized. More or less flat torque curve starting from about 3500 rpm. 500nm.

[diodelphi]

I regard Mr.Crawford

Here is a Dyno graph I found. Torque on the left and HP on the right. For the turbo they chose I think the numbers are good. It builds power quick, torque does fall off but HP stays pretty flat and comes on quick. To each their own. No need to bash companies for offering products. If you don't like what they offer then don't buy from them. I've been happy with my experience with Crawford and I have other friends who have as well.
