Hx40 Super Report

Istallation is not to bad to do. The exaust elbow will need to be modified or replaced and a compressor side outlet will have to be adapted to the existing intercooler piping. Spool up is only slightly slower than the stock turbo from 1100 rpm to 1600 rpm and after that it is just as fast. Cooling on the top is much better with full throttle runs to 125 mph from 60 mph egt was below 1200. [on the road not the dyno] running the power pup and EZ at max settings. Dyno runs at these settings averaged 432. 0 H. P. and 930 T. Q. a small shot of nitrous just to clean up some smoke netted 473. 8 H. P. and 1030 T. Q. Over all a good enhancement with out alot of trouble. RAY

How much boost are you running with it? How bad is the turbo bark?

Glad to here the turbo install finnished up well.

A truck that looks that good deserves a good turbo.

Will24; the boost is running about 30-35 psi, I am using the tst adj boost elbow and will adjust the waste gate to approx 40 psi but only after I try it with the tst box installed. Bark? none that I could discern and I came off of it hard a few times at the end of a nitrous run. So far I am very pleased. RAY

Billy ; thank you for the help I am glad that we had the time for the install . you had some nice numbers on the dyno and a nice looking rig also. If I can get an airdog or equivalent maybe I can get a little closer to your #s. RAY

thanks for the info. This turbo is on my list of potential future mods.

4wheels, just curious how you overrode the 108mph speed limiter.

By my math I have seen it several times... 315's being 13% off stock tires on the speedo, and I can hit 112-115 on the speedo with my TST and EZ. albeit I also saw 1650 EGT's.

Not too sure on that Vaughn, even stock it would run to 120 mph clocked on the street with radar and on the dynojetit will go to 127. RAY
