I managed to snag a spot in a local VW clubs dyno day last weekend. Needless to say, the VW guys would have probably been happier with their numbers if I wasn't there.

The only non-stock parts on the car are the nismo intakes which were put on by the dealer before I bought the car.

All 3 runs were done in 4th gear. The event was held at ET tuning in Union, Mo on a dyno jet.

HP 284.68
TQ 246.48

 

Wrong gear to dyno in. 1:1 gear is 5th.

 

good numbers

 

Nobody dyno's in 5th gear

 

Why's that seymore? I've heard people that do 4th and 5th

 

My tuner does all dynos/tunes in 5th.

 

they did mine in 4th

 

I don't see why you would dyno in a gear that's not 1:1

 

he did it and this is before i knew better....

 

This shop that I went to they tried to convince me that 4th is 1:1. I told them that its definitely 5th

 

how was their facility. I'm looking to get a tune there soon maybe.

 

5at 1:1 = 4th
6mt 1:1 = 5th

 

I have a few friends in the area who've already dyno'd in 4th so I stuck with 4th for a good comparison. I'll be back there sometime in May. I'll do a 4th gear pull and 5th gear pull so we can see the difference.

This was my first time to ET tuning and I liked the staff and facilities. I'll be doing minor bolt ons and a tune in May so I'll let you know how it goes.

 

I always do 1 in 4th and 2 in 5th. For comparison my stock numbers were 273 whp in 93 degree temp

 

Thanks OP for posting the dyno.

OT
How much do the numbers differ from running it in 1:1 vs not? I thought the dyno settings were able to compensate for non-1:1 ratios? Just curious. My hp was 272 with a 3rd gear run.

 

From what my tuner tells me, the dynos like to see a 1:1 gear for the most accurate numbers. For example, I changed my final drive to a 3.92 kit and I no longer have a true 1:1 gear so my numbers aren't 100% accurate. I made 303/272 with the stock final drive in the 1:1 gear, and with the 3.92 final drive I made 284/263.

He was telling me some cars don't even have 1:1 gears though (I think he mentioned the s2000 possibly?)

 

i hit 286 in 4th, wondering what it would hit in 5th.. might go see if i can do a couple runs

 

Thats what I don't get. I have 4.08 gears and it didn't mess my numbers up at all. Maybe it's only certain dyno machines I guess

 

Another reason my numbers IMHO where not what they should've been...

next time though...next time lol

 

I was always of the belief that dyno runs were done in 5th as the ratio for 5th is 1:1.
