Took it out this morning, it feels strong. Only running the 2.8 pulley currently, seen 15.5psi based on map readings and boost gauge showed 16.

Now I gotta get the 2.6” pulley on and see what it does.

 

Would be interesting to compare your 4" tube, 5" tube, and a velocity stack/bellmouth thing right on the TB.

 

I can compare 4-5” but haven’t done a velocity stack on throttlebody.

For comparison sake, at my location 97-98kpa is 1bar.

With a 2.8 pulley shifting at 6700

4” intake showed 201-202kpa and would taper off to 200-201kpa above 5800rpm

5” is 204-205kpa across the board.

With the 4” on the one time I spun it to 6900 boost fell to 197kpa by 6900


Generic pic but you can see Map Kpa barely moves.

I like the new tube. Smooth with no welds is nice!

 

Did my first launch with DBC. Launched at 1-2psi, no sense going higher with street tires.

 

Yes I had the dash trim removed. For some reason my tranny temp reading is acting up, still looking into it. Actual temp is good but reading is jacked. Temp sensor may be bad.

 

Looks strong as hell.

Can't wait to see it at the track.

 

I need to see how it launches with 17-18psi.

 

Wow, it launches hard. Do you have any suspension work done?

I miss the whine of a Maggie.

 

Stock just lowered. It transfers wieght good. The sound of it trying to grab and then not was a Expansion joint in my driveway.
