Boston Audi Dyno Results
https://forums.audiworld.com/a4/msgs/1151360.phtml
Interesting...
I would have really liked to have seen some 1.8T with different chips. It's kind of sad actually.
Yes, I know we have to take all results with a grain of salt.
From my Honda experience, the GSR with Greddy kit seems about right compared to the common dynojet 248 model.
Does anyone know why car #3 made so much power? Maybe it wasn't heat-soaked on that run?

Re: Boston Audi Dyno Results
FB,
Regarding the Integra:
Boost was raised at ~10.5 psi to produce 225hp. A/F was still rich - so more room to play.
What's the max hp (wheel) reported on a stock GSR with a turbo ? with reliability of course. To what psi can it be pushed before boom
At stock setting, ~7.5psi, the GSR ran ~185hp wheels.
Regarding the dyno:
That's one thing the owner was trying to explain to the audience. It's almost impossible to extrapolate to crank hp based on wheel hp since there are too many factors involved. If the numbers are low, they are low. A lot of people have been disappointed with the numbers when they try to compute crank hp. And it's MOOT to compare 2 cars with the same mod as they will differ. Turbocharged or normally aspirated.
The dyno is usually used to compare delta gains and tuning purposes and establishing a baseline before any mod is done. Typically 3 consecutive runs are taken on the same car to ensure repeatabilty among runs and weed out any freak occurence due to external conditions. And from what I have seen, the back to back runs are pretty consistent. On club days, this is impossible unless the rate goes up !!
That said, a perfect example is when the owner swapped his stock chip versus an MTM or APR or whatever. Voila, a delta gain is obtained on the same car - Does it match the claimed numbers by the chip tuner ? Typically YES !
For anyone interested in pursuing this discussion, please feel free.
Also, check www.i-club.com for feeback. They have dynoed several times also at Adrenalin and got pretty consistent results
Nice - 200hp wheels on a 1.8L .. not an easy feat.

A stock gsr engine can blow at 7psi or hold up to 20+ psi from a t4. Its all about tuning.
I know someone who runs 11.1@125mph on a stock engine in an integra and has done so for quite a while.
Also, the greddy kit sucks as far as reliability and hp goes. A t3/t4 kit can make 270+ whp at 9 psi.
