Thanks for all your input over the past month or so, I am heading to see Shawn today at 2:00 PM for dyno tuning. Anyone else in the area?

We are gonna stop at Alpine Village in Torrance for lunch today first, then to Church.

 

If you haven't left yet...what is he charging for a "non Z event" dyno. Maybe I'll show. I need one. Thanks.

 

I am not sure, he is charging me 160.00 per hour for tuning.

Call Shawn, I know I had to schedule some time before hand but that was because he is going to spend up to 2 hours on my car.

 

Wow, what an afternoon.. Got to Church and watched Shawn tune a couple Hondas. One little Civic was putting out over 250 whp normally aspirated.. Holy crap..

So we get my car on the dyno and he notices that I am only getting 5lbs of boost. I am having serious belt slip. He uses a little "carpet glue" spray on the belt and back to 8lbs. At 8lbs, the car put down a base run of 330 HP around 6600 or so. After an hour playing with maps, we were up to 390HP at the WHEELS.. The stock tune on the Split Second box had an A/F of 10.5-1. REALLY RICH.. He leaned out the mix a little in the lower range and set the top end at 11.8, the final run netted 400 WHP! I am very happy. I need to tension the belt now, need to find that somewhere.. I am sure it must be fairly simple, I am assuming the belt has a spring loaded tensioner that I can preload a little???

Anyway, need to get that belt tightened up then really need to get a boost gauge and A/F meter installed.

 

congrats on the #s...how many hrs did you spend on the rollers?

i been to churches once...and the staff is real friendly...we had a 15 car dyno day there, and everything went smoothly....i'd definitely recommend church's to anybody in the so cal area!

 

Shawn billed me $240 for 1.5 hours. Not bad as there was some down time between runs to let the car cool and play with numbers. He definitely knows what he is doing. When I got there he said that I should be putting down 390 to the wheels, I was hoping for 365 so was very impressed with 400.. I hear the DynaPack's register about 10 HP higher than the DynoJets..

What numbers did you get with your Maxima?

 

I actually didn't dyno at church's...I dynoed somewhere else on a dynojet 248c...my highest to date is 245whp and 247wtq...thats with the typical I/h/e and my Apex-i V-AFCII was running a mild tune...I probably could have squeezed extra 4-5whp with a more aggressive tune...

 

congrats derek, now fun times begin

 

Jeff, I need to get that belt tightened up a little, that or put some type of belt dressing on that will increase "stickiness" or grip. I am afraid to tighten up the belt much, not sure how tight I can make it without causing bearing failure with some of the accessories. Also, I am not sure where I can "raise"
the car to get underneath to tension the belt. Hell!

 

You dont really need to raise it up, but i guess it does help to get underneath. A serp belt is supposed to be tight, cog belt not so tite....stop worrying and just do it.
