I put the Z1 upper, Z1 25 row oil cooler with thermostatic switch, Shawn from synergy's lower, HKS GTR heat range 9 spark plugs gapped to .030, FUKU Works Upper and lower radiator hose. Havent driven the Z in 3 months, runs awesome. Goes to paint this week to blend in the panels along with the 2015 nismo front, skirts, and aerojacket rear spats. Driving to Portland when done for a retune. Then once back, time to put on the XP10's and XP8's, Z1's new slotted design front and rear 2 piece rotors, stainless brake and clutch lines, motul 600.

Well i got retuned today ended up with 317whp and 266 ftlbs, not as much as i expected but i did gain throughtout the whole powerband. Attachment 103880

309-259 baseline was what you had last year before the mods. So the new mods pretune, you made the same power?

No they didnt print out my baseline this time but he said it was 306 so i basically lost power thats compared to last year on the sheet

Nice thanx man, I'll be out that wat on the 6th. Auto Dynamics for a tune.

Lost WHP i doubt it to many factors for that such a small amount, I can tell you how mine comes out. I will go back the dyno I have been using for his whole thing after my tune. So we can compare apples to apples

Yeah i was skeptical too unless my motor isnt healthy, i may do a compression test

for 3 WHP stop it man LOL ,

You gained everywhere, What'd you think you'd make 330? I that's I HIGH number for us. The ones I see I think are just on a high dyno. Remember these re just numbers. You proved you mods made power just be happy. :)

Yeah im not upset the car feels great, but i may still do one to be safe.

Oh I may also be getting 1/4 mile times today.

You should LOL I bud of mine with almost the same mods are me( He has the M370) and tuned at Kaizen. He's going to the track up here tonight. He asked me to go too but I have to work late:shakes head:.

Damn, 18hp loss from 7 to 7800? Why, what mods?

Going to have to go with Scott on this one. Made more power for sure, don't know all what you have done all together or before this tune compared to after. Would be nice to see the graphs from the previous to see if the whole power band went left. I made 316std on just Gen3's, z1 tests, tomie y & y-back. All the way to 8k I was increasing in power. I can say I went on 2 different dynos in 2 different states and they were identical in power. STD correction and Smoothing of 5. I went by the paint shop yesterday to provide more detailed pictures of the 2015 nismo paint job regarding cut off lines and such, so when that gets done and I get the XP10's and 8's in and throw on the 2 piece front and rear rotors I am heading 3 hrs for the tune. Probably looking at 3 weeks from now I figure to see what the new lower, z1 upper, green filters, and heat range 9 HKs plugs do.

1. Everyone should look at SAE as well as STD; STD tends to inflate estimates on N/A cars.

2. Also take note of weather, air pressure, and actual correction factor value. Expect massive losses with higher heat and humidity that will not be perfectly compensated for by any correction factor.

3. Keeping the above two points in mind, you should be able to make reasonably good comparisons between dynojets. Dynojets calculate hp based on the rate the drum is accelerated; tq is reverse calculated on the basis of hp with a dynojet.

Nismolucino, you do not need to do a compression test. Your motor is fine.

Also, that's just from TB's and a tune? Those are excellent gains.

Thats from tbs, ported upper and lower, under drive pulleys, and clutch and flywheel (which i know doesn't add power) thats all the changes Ive done this year. What bothers me is that my friend had his nismo tuned today right after me at r/t. He has fi catback, test pipes, and stillen g3s and put down 316 whp and 259 ftlbs. However even though my hp is lower than expected, my car is putting down a decent amount of torque. Im still going to do the compression test just to be safe. I did go to the track today but it didnt go well so the times aren't even worth mentioning. Im still dialing in the grab point with my csc elimination kit and it was the first time at the track with it. I have clutch engagement issues, I cant power shift into 2nd or 3rd, but it does fine when I ease into the gears. All the times I power shifted it locked me out of 3rd and I grinded 2nd one time. Im thinking I may have to remove my rjm clutch pedal, it may be too much adjustment now with the adjustable external slave cylinder. Im going to try swapping my factory pedal and see if that changes anything.

these are the mods
Stillen Gen 3 Intakes
Bored Throttle Bodies by Maxbore
Ported Upper & Lower Intake Manifold by Synergy
ARK Grip V2 Catback Exhaust W/ Burnt Tips
CNT Racing Resonated Test Pipes
NST Underdrive Pulleys

that dyno graph shows my current numbers compared to last years dyno graph(thats what the lower lines are, not today's baseline) Last year the mods were
Stillen Gen 3 Intakes
ARK Grip V2 Catback Exhaust W/ Burnt Tips
CNT Racing Resonated Test Pipes
and with that I put down 309whp and 259 ftlbs.

Im curious as to why my power drops too scott. It was like that last tune too so its not something to do with the new mods. Im starting to lean towards the test pipes.
