Monday noon, parts "will be installed in afternoon".
Monday 3PM, parts "dyno'd and tested"

Done by a competent mechanic.

Sounds easy then

hahahah that's what I get for telling Kojima to "hurry up and write an article" so he can get first dibs on this.

He did mention that, for whatever reason, my car was the strongest stock FA20 they've seen on the SuperFlow yet. I don't feel my engine is particularly powerful, but I guess numbers don't lie.

FACTORY FREAK

All jokes aside, I'll see what their schedule is to run perhaps another dyno test in a few weeks to see if the power stuck around. Very curious on whether this is just a fluke part or not.

This is very interesting!

Be even more interested in finding how it goes with headers, full exhaust and a tune.

[troek]

very good stuff!

[mad_sb]

Gains look good. That area from about 4750 to 6000 is difficult to find gains on this platform without boost. Headers, full exhaust, tuning, E85.. all seem to give lower gains in the 4.75k to 6.0k range than the rest of the power band.

Really want to see how this does with headers and a full exhaust.

If there are any socal shops that want to test these both with a 4-1 long-tube header + full exhaust AND a Nameless 4-2-1 coated header + full exhaust... shoot me a PM. My Nameless header is sitting the garage waiting to replace the 4-1.

Yeah this looks like it would pair very well with the Nameless 4-2-1 EL header based on that dyno.

- Nameless has really strong gains from 3600-6000 rpm compared with a typical UEL header.
- Crawford has nice gains from 2000-3000 rpm, then 5700-6500 rpm.

These two combined could possibly give you significant gains through nearly the entire RPM band.

Anyone know if this will fit with a vortech supercharger?

[Scottemad123]

I waiting to see if the ECU will try to tune out the gains like usual.

[troek]

i doubt it would fit without some fabrication of ur intake piping as it would raise the throttle body out of alignment with the factory vortech piping.
maybe theres enough play in the piping though?

Good review, just wish their dyno included the AFR as well.

Not to be a negative nelly, but 4whp is a far cry from the claimed 19hp. Yes the area under the curve increase is far more impressive than the peak hp gain suggests, but it leads me to suspect that the crawford dyno with the PB was a tuned run vs a totally stock car on the baseline.
