I've just fitted Harvey's up-pipe for GT Spec headers and also experienced more low down and midrange torque. However, like you, we also found (on Zen's rollers) a slight drop off in power (about 10bhp) over 6500rpm. I use a Hyperflow wing-mounted air intake so maybe it's something inherent in the up-pipe design?
Cheers, Andrew
Cheers, Andrew
Mark, what sort of power and torque would I expect from a 2.1 with MD321H?

If you guys are running around 400 bhp with inner wing filters I suggest you fit a bigger filter and find out what happens.
One uppipe design will not cater for a range of specifications which is why I actually have four uppipe designs. The trick is in selecting the right uppipe. During the substantial testing what we did find was that the air filter size had to be increased.

Cheers Harvey - food for thought as ever 
(although still doesn't explain why on dyno runs on same day before and after fittng your up-pipe I experienced a slight drop in top end power with the SAME air filter [still prefer the power delivery with your up-pipe tho])

Trust me. If the uppipe makes a big difference which my special 3 bolt flange uppipe does you need to ingest more air and I have proven that on a number of occasions.
Have a word with Paul Armin. He picked up about 20 bhp just by putting on a bigger filter although he was sceptical about what I was telling him in the first place.

Harvey, I'm in the same situation - inner wing filter that was supplied with Hybrid FMIC. Can a larger inner wing filter be fitted, or do I buy something like the RCM cone and fit under bonnet?
Has anyone fitted an RCM cone with Hybrid FMIC? It looks like the FMIC pipework might be in the way?

I would be intrested in this as well, still got the 20G but was thinking about the 321H, Im guessing with a forged build and more boost 420-430 is do able and maybe as high as 450-460 with methanol or E85?

RCM cone looks bloody tight. Will post a new thread asking if anyone has fitted under bonnet filter with Hybrid FMIC.

I think with a forged build 400LBFT should be more than do able with 2 bar of boost, going to be using it with a 2.1 stroker in mine so should hopefully generate a bit more torque than a 2.0, If i was too see 450-460 with a drop of methanol or E85 i would be happy with that

Ive been running 422bhp / 400lbs (@ 4200 rpm) on my std 2 ltr wr1 block at 1.8 bar without any probs - all managed by a solaris ecu.

An update to this old thread, finally got around to fitting the Syvecs ECU yesterday, bigger under bonnet filter, 3 BAR map sensor and Wideband. Pat was in charge of programming ECU with his usual high level of detail 
After mapping the meths in, we went for a test drive what a difference 60lbft makes! After some tweaking on the launch control Pat suggested proper test, I haven't grinned that much in ages. Awesome. Turbo whistling holding just under 1BAR stationary, pops and bangs out the other end then wollop, all four wheels light up and no bog down at all
ECUTEK (lower power running 1.55 BAR) and Syvecs V-Power + 16% meths (1.7 BAR midrange, full power made at same 1.5BAR)
Syvecs 1.4Bar midrange V-Power vs Syvecs 1.7Bar midrange V-Power + 16% meths (I know it not a fair comparison, need to get more graphs from Charlie)
Boost graph for the above
Fuelling, V-Power vs V-Power + Meths

Yeah, I was quizing running MD321V on 2 litre. Not sure which way to go for next turbo, probably MD321T billet.
That car you mapped was a beast, 585bhp on V-Power
About the launch control I was asking Pat that presumably the charge air isn't cooled that much by the FMIC and he said to not hold it on too long. Couldn't the ECU turn on the rad fan, that might help the situation?

if you watch boost gauge the boost will build and hit max boost on the lauinch control about 5 to 10seconds etc.. no point holding it longer...
it can be an issue when waiting on lights on strip to time it right mind.

The trick with launch control is to have the temps at working temp but as low as possible, no heat soak. For instance at the strip you can spray a gardeners water mist / spray on the FMIC core repeatedly from your previous run to take the heat out of your FMIC or TMIC core. You can pack a TMIC core with dry ice but it has to be removed prior to staging. Bonnet open to allow heat to disipate. Turbo exhaust heat wrapped. Intercooler pipes to T.B. insulated. run engine about 2k rpm for 20 secs to get fresh air in.
I very much doubt the radiator cooling fans will have a noticable effect on ACTs but they do help pull down the water temperature.
Water methanol spray pre TB helps tremendously.

The issue is not just charge temp though.. the exhaust valves, headers and turbo will get very hot..

Appreciate there's more to it than that though.
