Going Single after 10 years / SP F1 Manifold, PTE6265 by Josh S

3 minute(s) of a 66 minute read

Well good news. I went down to the garage this morning to double check a few things and I found that I had connected the pressure source to the top of the rear gate by mistake. So only the new front gate was actually opening hence the same creep as I saw before with only one gate.  

I will correct this and give it another go when I get home from work tonight. Looks like everything should be fine I just made a stupid mistake with the hoses.

Just got back from my test drive, it holds a solid 18-19psi now with no noticeable creep I think I'm going to going to go down just a little on wastegate spring pressure to bring my base boost down a couple of psi, but it is running well right now. Will be scheduling a dyno session soon.

Made it back to the dyno. With my boost leak issue fixed I picked up much better spool. Below is a dyno comparing my last year's pull with my new pull, both at 24psi on pump gas + meth. I'm surprised at the torque it is putting out now, this was also a very hot day and the engine was heat soaked with only a few minutes cool down. Spool feels much better on the street now as well.

Took the Supra on the North East Rally with 21 other cars last weekend. Covered 1400 "spirited" miles and 5 states over 3 days. Beat on the car pretty good and it performed great, no issues at all other than I need to tweak my decel fuel cut settings a little bit as the car wanted to buck at about 2k when costing down.  

Did get my first ticket ever in the supra, got pulled over about 45 minutes into the rally while only doing 65 and got a ticket for no front plate. Car was stickered up so it stood out more than usual.  

Couple of pictures from the trip:
