intake temps plays a big role in making or losing power, 1 psi more of boost gives u x% more power, lower ur intake temps say 10 degrees will give you x% more power if u keep the pressure the same.
 
sidemount IC(without some sort of fan/cooling blowing thru it) = heatsoak/ high intake temps/lower than expected potential power
 
front mount IC with fans blowing thru it will always be a better set up
that's why a lot of mr2 big power builders change over to w2a set up to try counteract heatsoak and get better intake temps
 

lol... here we go.
i agree, it's certainly easier doing up just about anything else..... having the engine in the front with decent access, having a front intercooler, parts availability, and every second mechanic reckons they know SR20's and EJ20's... and a bajillion boy racers who have tried and failed to learn from.
 
I reckon that lot makes a bigger difference than any stock differences between a 3S, SR, EJ, or 4G.
 
shootout mode is great...  i think Dyno Dynamics in shootout gives you the best indication but there are still a FEW variables (different modes)... when mine got done last (in shootout) my mech had just changed his dyno to 4wd and cars that HAD been reading 245&260kw on the 2wd were getting 215 & 230kw... pretty consistent 30kw down from the 2wd dynodynamics in shootout. I'm not sure (possible teething problems  with new dyno, i'll have to see if it's sorted now) and there's always air temps... Dyno's are a tuning tool and good for a laugh, a sausage sizzle and discussion.

1 thing to remember is that a dyno day is about having some fun, hearing some engines being given a hard time and chatting with everyone. Although my car made 345.1 rwkw i wouldnt have cared if it made less, i would just be happy to see how the engine/car is going. Cars don't stay at the same power level forever.

I think that's exactly what a Club Dyno Day should be all about.
Turbo's not making enough power??
My car is an old stock Gen2 3sge NA and I was surprised to even get 92.8 kw ha ha.
 

SR20 might make easy power but it is very poorly designed in comparison to the 3S asides from the fact that it is alloy block with floating bores.
 
Tthe cam gear setup is poo just like the cam angle sensor that almost 80-90% of fail, and anything beyond 200kw you need to pull the motor out and get the bores re-sleeved as the stock ones are weak.
 
What's a common fail on the 3S? ohh wait it's the sound of silence

Monaro not a MR2 sadly.

Red you managed to get a pic of me in action LOL
I was actually just about to transition into a head-spin > notice the guy staring at me to the left lmao "this kent for real?" and the guy to the far right "this should be good..." sarcastically.
Also Red I'm curious to see your graph as well to see how my old engine would have performed.

lmt

only numbers to indicate true performance are 1/4 mile times.
there are still too many variables on the dyno to compare one car to another.

Many years ago, we had a mr2 vs supra 1/4 day.
our poor ct20b 200kw mr2 gave all the 300kw+ supra an embarrassing lesson.


Dyno are great at adjusting your timing maps and cam adjustments.

Maybe sometime next year we should run a 1/4 drag day. Be interesting to see how some of the cars and drivers perform. Thats if anyone would be interested in finding out how their cars actual performance is.
