I suspect that low power reading would have been done after back to back runs to show how much power it makes once the top mount intercooler is heat soaked already, so the 35kw increase possibly isn't as good as it sounds. More that with a FMIC it can actually maintain that power, not degrade pull after pull. The lag/response difference (or lack of) is some proof I hadn't seen before.

hah! truth is I met my wife through CS aprox just over 7 years ago.....

Would you flog it on the top, or front? NAIHOC forums (North American horse owner's club) hotly debate that at the moment.

They should come with front mounts from new..

Seems like hard work... I'll stick to mail order.

Flogging a dead horse lol Front mount is always better. But isn't needed until you're pushing 220+wkw . Ducting and shrouds are a must in any efficient top mount setup . The whole lag argument has been debunked sooooooo many times. You lose like 200rpm switching from front to top, but gain probably 20wkw anyway. Big turbos are laggy, front mounts have nothing to do with it.

But hood scoop

See Prestige Tuning & Motorsport's post on facebook today? Additional front mount lag looks like 100rpm or so. Factory location turbo and manifold, basically longest routing and large volume to fill. Given those results I'd be trying to get as little pressure drop and not really be concerned with volume to fill (with in reason), so 2.75" all round shouldn't hurt.

be good to put faces to internet names! that's the best part about this sort of weekend

tbh if I was being passed by someone it was usually my fault, not the car's haha

Has anyone seen the post by Prestige Tuning & Motorsport on facebook in regards to this question? if not you should go check it out! They just had a GC8 in with some motor work and a Tomei turbo on it and completed a dyno run with the (process west) TMIC. then they fitted a Process west FMIC and on the same boost gained an extra 35kw with the air temps maintaining 26 - 28 degrees through the power runs. Was so cool to see a dyno proven result on this topic. If someone isnt a computer noob like myself please copy the article to here ha ha

No, Alexandra Road hillclimb and Wallaceville Hillclimb. No green wheels on those days.

we tuned the same turbo on a factory top mount runinng 260kw and just a little bit less boost(didnt push more power as after 3rd run it was showing heat soak) will do a fmic next and then hoping to do 270-280kw on the same boost due to better cooling (this car gives me hope )

Yeah there’s definitely a hell of a lot more to it than just viscosity, but having the correct thickness at running temp is a good starting point to ensure everything that is pressure dependant works as expected.

Have a long 14mm offset ringspanner helps. Don't forget to do up the clamp on the oil drain before starting it. Replace the copper washers or anneal them. Oooh and if you want to be nice to the turbo pull the fuel pump fuse out and crank it over to prime the turbo with oil before starting it.

Yeah be good to finally meet you @Joker

True there will a big part in how they tested. Would be nice to know if they intended to write that up before they started. hopefully it was an honest comparison, but at least it was same brand of cooler. even still with all the pipe work and massive cooler the front mount still looks like a better deal. would like to see the stock cooler as well

Very true had not thought of this, thanks for pointing that out. makes sense though! if that is the case it would be good to know the non heat soaked numbers to see if there was much of a gain.

@mlracing.co.nz posted some under Process west @pl0x embedded it in the topic on Intercooler piping seems like for the $550 difference between the two coolers it's worth it. id like to know how much work is involved in installing the front mount though as top mount is super quick to swap. Plus hard to see from photo if the stock BOV mount is still there.

lols... it doesn't really matter... the point is that both numbers mean something... and it's not just down to the umm quality and umm the specific additives etc

depends on the turbo - we had a rotated greddy td06 (@304kw) and that was punchy on the low end as well (very similar to the vf30 with a touch more lag maybe like 300rpm) but in higher rpm was almost the same feel the chinese td05 do have noticeably more lag but for the cost they cant be considered bad...

So true! I am going to go with a stock location turbo i think just to get a bit more punchy power rather than chasing the 300kw figure haha. At the Chrome expression session at manfield I noticed the power band difference quite a lot with coming out of the corner onto the front straight next to a high KW big turbo evo / wrx and them only passing me 3/4 down the straight as I was on boost and not falling out of it from the moment my foot hit the floor. I definitely think it depends what you are wanting the car for but it was quite interesting to see car vs car. I am sure @calebwrx would of noticed this also.

Cheers @Joker I was still waiting for leave that far back so wasn't looking at it then.
