Pretty impressive gains.

This is really impressive!
 
Impressive indeed. That’s Kong’s max effort ported blower. They need to toss a 2650 on there next and see what that does.
 
AFR's were in a great spot already. Imagine how much more could be squeezed with a proper tune all the way through. It was still pulling hard at redline too! Add a header and maybe a pulley and this could be crazy upgrades to power.
 
Maybe a novice question but is the ECU just dynamic enough to recognize and fully accommodate this or does it really not need to do anything more than call for more fuel with the extra air? Ported blower is a pretty easy and safe 60whp it seems if everything else will hold up without a 'proper' tune
 

Runs start around 6:45

Track time with the ported blower and drag radials. Interesting to see different starting techniques. Managed a 10.99
 
Amazing. If tuning eventually becomes available, we can only wonder how much more to squeeze.

When the learned folks say it’ll never be tunable (HPTuners, Cobb, etc) I believe them.

I know one aspect is the ECU (misnomer since it now isn’t one box) ‘calls home’ to GM and runs a chksum every 24 hours.
 
Spoke to them about blower returned car so owner can drive it for 2 weeks make sure no check engine light.
Then change pulley hopes to make HP, at some point fuel will become an issue

Reviving this old thread to see if anybody else has done this since then and had similar results.

Honestly, this seems like a pretty good bang-for-the-buck mod. If you can pick up around 50–60 whp from just porting the stock blower, the money spent vs. power gained seems pretty solid compared to going with a bigger supercharger or getting into cams, pulleys, headers, etc. Especially if the whole job can be done for around $3K.

Has anybody else done just the ported blower and gotten similar results? Curious to see if others have picked up around the same horsepower from this single mod.

You won't gain 50-60whp, you will see around 30whp without a tune on a stock car You will gain more with a tune. The trap speed just isn't there to support that the car gained 60whp. An X-port will show a lot more gains on a highly modified Blackwing.

That makes sense. The 50–60 whp in the original video is what really caught my attention, but around 30 whp on a stock car sounds more realistic based on what I’ve been hearing. Still seems like a pretty solid mod, especially if it benefits more as you add other mods later.
