Blitz Return Flow Fmic

[TR33GT-001]

Guys,

I have now finished off the R34 GTT with the East Bear Masterpiece Collection GTT to GTR bodykit.

All other work is completed except for the FMIC.

I want to use the return flow type, to retain the "over the engine" style intake.

http://www.kudosmoto...-neo-p-944.html

I am going to use the intercooler linked above.

I'd like to get some feedback from the members who have installed this unit in the past.

Has it bettered your response or not?

My car is running factory intake and airbox with an HKS panel filter.

The turbo has been hi flowed and is running a modest 10 psi, making 335HP at the fly wheel.

My aim is to better the response, and cool the air better, not more power.

Has anyone found that installing one of these units, actually increases lag?

Many thanks.

Jim

Hey mate, cant say i noticed a difference with lag or response, it pretty much didnt change, although i'd def recommend one if you do chose to increase your power down the track, especially with a hiflow turbo.

Cooling the air better is how they make more power.

What are you comparing it with? Do you have a fmic now or the standard GTT smic?

I had a Trust smic (bit bigger than the GTT one) on my Stagea making about 220awkw and changed to a Just Jap return flow making 240awkw with a GCG highflowed GTST turbo on about one bar. I didn't notice any increase in lag but then there was a power increase as well.

I have now changed to an HDi Hybrid fmic with a Greddy copy FF plenum on an RB30 so can't notice any increase in lag or response.

If you have the GTT smic now there will be no improvement in lag but it should be easier to make power.

If you have a fmic now I doubt that you will notice any improvements.

[TR33GT-001]

It's presently the OEM SMIC.

I'll wait for a few more replies before deciding.

Thanks for your comments so far guys.

(I'm being overly cautious, for good reason. Money!)

That's a pretty good power figure for the stock smic.

I've always said they were underrated. People used to go on about heatsoak but that was only ever a problem for me on the dyno - not on the street or track.

Having said that I think the Blitz return flow is a good unit and you could wind your highflow up a few psi and you will notice a good power gain with no noticeable downside.

You could save a few bucks by getting this one instead (the one I had) http://justjap.com/store/product.php?productid=17355&cat=0&page=1

But if money is really tight you could carry on as you are until you are ready to upgrade.

You will see a slight pressure drop it's way bigger the stock cooler your also adding piping but would be hardly noticeable but thats my 2c it is a deffinent improvement over stock the gains will out weigh the cons

[gotRICE?]

I have the Blitz LM on mine. Didnt notice any decrease in throttle response or any increase in lag with the stock turbo.

Putting 300rwkw through it now with no dramas. Keeps the intake temps very low. And removes temps very quick if it heats up in traffic etc. It will drop 20+ degrees in a matter of seconds. Even just giving the throttle a stab and holding the revs a bit higher at a standstill the temps plummet.

On the track on a warm day the temps range from 25-35'C giving it full beans. On the road it, 18-25'C.

[Kenna802]

Over 2 Hours on the Dyno, Tuning and Power Runs and Return line was still Cool

[jet2nv]

im using a big ARC return flow dont know to much about them but have heard after a car was tuned by trent after 15 runs the intake temps didnt change at all

and have seen a few results make over 300rwkw with no problems

havent looked into the other brands much so cant really comment on them and i cant say if i noticed a difference as my car came from japan with it fitted

but when my car was stock with full 3 inch stainless dump pipe and exhaust,metal intake pipe 9psi i raced my friends r33 with excatly the same mods except the intercooler he was using a just jap one

head to head i was 2, 2.5 car lengths in front

not sure if that was the coolers doin or not

hope this helps

[Bsa]

Has to be the driver on that one

[jet2nv]

ARC claim to have a 60-80hp gain when fitting the return flow cooler they did have dyno results on there website but its a shame they are gone now

[boostn0199]

Lol companies always give redicolous power increases that will never happen. A cooler isnt a power increasing mod like rurbo its a mod like fuel pump it removes a restriction and allows you to get more power out of the pther mods like a turbo.

[jet2nv]

there was a comparision on a thread on here same car back to back test one with a jjr return flow and one with a arc made 80hp more

[boostn0199]

At what power level though? up to around 300kw they will both be the same its only once the jjr starts to reach its limits and be a restriction is when that could happen. For instance if its just a relatively standard car and you put one on you wont expect a power increase of 80hp,

[jet2nv]

main difference ive seen with the arc coolers compared to the rest is after 15-20 dyno runs the intake temps havent moved and the arc cooler is cold on both sides i know as i have one and tested it

but dont get me wrong im sure all the other return flows will be good just saying if this guy can find one i wouldnt think twice snapping it up i was lucky my car came from japan with it fitted i wouldnt like to pay 2-3k for a return flow cooler hahah

[boostn0199]

Yeah I agree the ARC and other jap brand coolers are better than the china ones and will keep temps down better if I have to buy one again it will be a jap brand, I was more trying to point out the fact that some people think a intercooler is a instant power mod.

[jet2nv]

no i dont agree its a complete instant power mod i do know when i drove my car with just a stock sidemount it was pretty crap then i fitted the arc back on and could skate 1st and 2nd very easily

[TR33GT-001]

Yep, an intercooler is a supporting mod only, for the intended power level that is targetted. All good guys. I am going with the Blitz unit, as part of the final mods. Thank you all.

killer cooler the blitz return type.

[def_jamz112]

Good to hear the blitz turnflows are good for up to 300kw? but how would it compare to the cooling pro option from justjap?

I was set on getting a black cooling pro but im just worried that its not going to be up to the job.

I should also mention I'm planing on getting a HG turbo later in the year and i want to make the right choice now so there are no hassles(i.e. struggling to make the most out of it) later on when tuning the thing.

Thoughts on either cooler for 250 ~ 300 kw applications? - as you can see i havn't yet chosen my ideal setup.
