From: South Wales, Scoobless, Type R is gone!
There is a later design of hybrid which has a tube and fin core that is the exact same size 600x300x75
It is lighter and higher flowing, you only need to pick one up to tell there is a significant difference.
The core I refer to is the one you changed over to use on your own WRX last year, not the 95mm thick 'monster' core.
For others benefit, the easy way to identify them is the more efficient tube/fin has a rounded edge and the bar/plate has a sharp square edge to the cores.

I've just ordered one for my car to replace my autobahn88 kit, coz i think this is the reason my car had low figures compared to others on here with simular setup's.
I run a VF34 with supporting mods and only made 312bhp and around 260lb/ft of torque, where as most people running VF34 setup's are making 330-350bhp and aorund 300lb/ft of torque.
Won't be able to tell 100% if this is the cause as i will have also added an AVCR, 550 injectors and be running a fuel additive when it's mapped by Andy again in May.

the pipes are all good, i have put the bolt style clamps on, one join did have a slight leak, but i refitted it and all seams to be good now (this was all done before the rr)

okay cool..
if you are not able to get AFR or boost plot from the run on these rollers to help out further then it would be worth taking it to another set of rollers or I should check it over.

For 1.35 bar on the plenum, what was the turbo having to boost to ?
23 to achieve 20 psi ?
3psi is worth approx 30bhp at 6000 rpm in my experience.

What intercooler do you have Micky ? Thats an excellent result for 380cc injectors and 1 bar of boost ! Is that without any octane booster ?
I'd be a bit wary of running it hard on a cold day though as your injectors have maxed out from approx 5300 upwards, if you get a denser airflow then you have no more fuel to add, you will run lean and may melt something.

My intercooler is the Autobahn one from Flat4online. Forgot to include it.
Ran with a litre of Silkolene Pro boost and V-Power.
I've got some 440cc injectors to have fitted, when they've been flow checked, not sure if it wouldn't run like a dog though.

My car, MY94 WRX, made 330.1 bhp and 289 lb/ft on the Dastek RR at Motoscope in Northallerton last Sunday.
My spec:
Standard EJ20 engine
Standard engine management, Z4 Ecu, unchipped AFAIK although I should take the cover off and have a look.
Standard TD05-16g turbo
Standard 380(?)cc injectors
Standard headers
GReddy Profec B Spec II boost controller, running roughly 1bar of boost.
Magnex up-pipe
Revolution downpipe
Blitz Nur Spec R
Apexi Power Intake
Walbro fuel pump
Graphs:
Power and Torque
Boost AFR etc
Everything stated as standard above is as it was when I bought the car 2 years ago, anything that may have been changed before that I don't know. Apart from the Z4 ecu which was purchased from Grade A last summer.
So, to increase my torque level, I should have my headers ported. Think I read it right.

just checked through the map and log files.. all looks very good.. it took a lot of timing.. boost tails to 1.2bar about 6200rpm.. took a lot of timing when mapped.. something must have altered somewhere?
Have seen ne injectors richen up as the storage fluid in them cleans out but I still don't think it would be enough to cause a drop in power this much if the rollers reproduced how it actually runs on the road..
I need to check it over Ian..

ok,
the garage has put a good copy of the RR graph in the post for me, and hopefully i will have it soon

Spooled very late.. either the load was very unrealistic on the rollers or there is a boost leak somewhere or similar.
When does it spool on the road now? should be 3xxxrpm.. not over 4k like it is on the graph there.

I ran early on that same day and also had slightly lower figures than I expected from DD Road Dyno runs. Gave me 356/402 - rollers are fine but there is no real cooling for Top Mounts although that wouldnt have affected you DaOne.
For torque, you cant beat a 2.5 but from looking at the graphs it does look like it has a really late boost issue - not wheel spin was it - did you run when it was raining?

have just been out in the car, 4th gear putting foot down at around 2k reves
0.70 boost @ 3140 revs
0.76 boost @ 3167 revs
1.32 boost @ 4237 revs
1.33 boost @ 3910 revs
1.33 boost @ 4251 revs
what can you tell from this?
boost is on 1.3 setting on the apexi commander
0.70 boost @ 3140 revs

1.32 boost @ 4237 revs
1.33 boost @ 3910 revs

will have a check for what reves it hits 1bar later, yes 1.3 @ 3910
the only things different i have done since remap is put the better hose clamps on, and they all look good.
how else can i tell where the leak is coming from?
