My ported and rebuilt gen 5 blower finally arrived today.

See pics:
Pic 1 is parts on the ground at 6:30 P.M.

Pic 2 is showing the ported blower (steigmeier port, but High Speed Lab rebuild and rotor coatings) with special rotor coatings from The High Speed Lab that are immune to meth, fuel, etc. The port may not look like much, but the "v" is 4mm wider at almost each spot, and the inlet was ported too, so approx 10%? larger openings and now the intake and outlet are supposedly well balanced. This should be of some use when I add the +4 lb lower pulley soon. This will spin the rotors 14,500 rpm at 6000 rpm. Supposedly cavitation starts around 17,800 rpm, so I'll stay more conservatively cooler and only do the lower pulley.

Pics 3 and 4 are showing the car running smooth as a sewing machine at 9:00! It took only two hours to assemble and find my two vacuum leaks (brake booster hose not installed-duh, and one of the billows/seals was sucked in) and then 1/2 hour to fix the 2 air leaks to get it all running perfectly! No codes! I am relieved.

Took her out for a quick spin. Very smooth, but I can tell the intake is really holding her back. This will be fixed in the next week.

Pic 5 is the Pretty Kitty after her maiden voyage. The boost gauge is holding 10 lbs solid from 4500 rpm to redline with no drop off with the stock intake. Now that I have no codes I am going to add:

92mm MAF and 4" to 3.5" intake tube (curious to see what this does to my boost gauge reading) <--maybe +1 lb of boost?

Water/meth injection (also curious what this will do to my boost gauge reading) <---maybe +1-2 lbs of boost??

Oil Catch can

Nameless performance Cat, and add wide band AFR gauge

Kenne Bell Boost-A-Pump


then run a Dyno

then:
+4 lb lower pulley
Tune: to remove maybe 4 degrees of timing, raise the rev limiter to 6500, delete the 155 top speed limiter, target better AFR

Then it will be off to the racetrack and dyno.

At any rate, it is good to have an XJR on the road again, it has been too long.

I am very relieved to have been able to get it all back together and running perfectly in only a few hours. I had changed a lot of things, so if there were any problems, it could have been difficult to find them. The two air leaks were loud so they were easy to find and correct.

 

Very nice! What kind of boost pressure would a stock XJR produce?

 

Wow! Well done!

 

I have never seen anything other than 9.5-10 lbs on a stock pulley set up with the stock intake air box and intake tube.

I know the "spec" says 11.6 psi, but 100% of the people I've talked to about it say they see no more than 10 psi on a reliable gauge.

I am currently running the stock pulleys, and as the photos show, the stock intake.

 

If I remember correctly you may actually lower your boost a little with the porting but pick up efficiency. You may want to ask Bob about that.

 

Will do

Did you see a boost gain by running the water injection before the blower? And if so, how much? I know you were running the 625 ml/min, whereas I will be only running 375 to start with.

 

Wow - very cool!
