Stig is there a reason why you are using the turbo cams over the supercharged, or is there no difference??

He is running the dbilas z22se turbo kit

 

 

 

The dirty bastard

[Exmantaa]

We had a dyno run yesterday with some speedsters, and one was with the 2.0 Z20NET (=B207)

He was running very hot in intake temps earlier this summer (up to 90), before fitting water injection.

He's the first going on the dyno with a large pully though i believe.

 

So he did 306hp with an 80mm / 3.15" pully (1.38bar/20.0psi) (2.0 with harrop)

Ultimate did 330hp with a 75mm / 2.95" pully (1.55bar/22.4psi) He is now on a 70mm but no dyno yet. (2.0 with harrop)

 

What were the numbers again the Uk smaller pully dyno sessions did? (include 2.2 or 2.0 and M62 or harrop)

 

 

 

Also makes you think larger pully does not help that much with intake temps when on track.

 

 

Some graphs to this:

Stock Z20NET engine, balancer delete, lichtened flywheel. Exh. ported head + valve springs. Harrop SC with 80mm pulley, PA pre-rad and a Tullett 2,5 system with decat pipe. Water injection above 1 bar boost to combat the IAT's. LSJ ecu; road-tuned with HPTuners.

 

 

And a note to the >100BHP drive loss; this is a MAHA bank where the double rollers and the roller loading give those high loss numbers. The drive loss seem to be measured accurately to give correct engine power. Just don't look to the wheel power curve...

Ow, rpm calibration was off, as the limiter was at 7600rpm. Not sure if power should be corrected for that. Also airfilter temp started @ 25*C and the run ended with 29*C air temps

 

See this HPTuners log of the same run:

 

Fuelling was quite spot-on for an 11.8 commanded AFR @ WOT. Max rpm was 7600 and also interesting is the little knock retard that shows as a little dip in the dyno curves. Water injection is doing it's work to keep IAT2 down, but still above 50*C after the SC. :-/

Water injektion or water / methanol / ethanol injektion? Wich system? Snowperformance? I am looking forward to my own Harrop;)

[Exmantaa]

Just water. Self build system with Aquamist pump.

 

(Note; we found out that the HPTuners datalogger is maxed out at a 255km/h speed value. )

😃 but it works. Under 60 degree is okay in my opinion!

[Mr Apex]

To solve the IAT and manifold problem, I think that the best solution might be to move the SC. there is no space to carry out efficient cooling between the SC and the head and the SC sits high up, raising the roll centre. Why not try to situate the SC low down, then use turbo style intercoolers to get rid of the heat? Then you could use a more conventional turbo inlet manifold to supply boosted, cooled air to the head.

i mean turbo style is no opinion as the ways get too long. so we lost the nearly perfekt throtle response

Thats not true. The 332hp Run was only 1,2bar boost with the 75mm pulley. Probably belt slip and the short acceleration time on dyno. Same set up boosted 1,45bar on street. I am now running 70mm pulley. Not dynoed yet but run 100-200kmh gps measured 7,5seconds ;-)

[Exmantaa]

When is your new dyno with the 6-rib planned?

(did you have cams fitted?)

[CHILL Gone DUTCH]

Any updates from anyone? My build is moving along smoothly and hoping to have it all running early next year in a quiet time with work

[Tony H]

Mine's still in the living room.

 

Are we doing any group buys yet?

conversion bits

[CHILL Gone DUTCH]

1. Chill. 2.2 crank, forged pistons and rods stage 2 LSJ cams,lightened flywheel and balancer delete, home build with vocky input on Dutch ECU software M62 charger ported head. Hoping for 300+ 2. Graeme. 2.0 Saab B207 with standard pistons and crank, Comp cams, chenge of flywheel (Vectra V6?) which may as well be lightened and balancer delete, plus whatever else Vock recommends (within reason) using M62 and dutch software (or standalone) and I'll be happy with 280-300bhp 3. Westkenbrit. Vocky fettled B207 (ported etc..), 2.2 crank, forged internals, siemens injectors, stage 2 cams (unless advised otherwise by Vocky) uprated clutch, dutch software, harrop, Pro alloy chargecooler, and baffled fuel tank, uprated fuel pump. 350+ But Neil and Joe would know better as they are doing it all 4. Chris. Leave it sat in my back garden until i can be bothered to pull it to bits. 5. Tony. Ornament. Going to collect all the adaptations and that while I decide what to do. 6. Smiley. 2.0 with head exhaust part ported, zzp or comps cams, lightened flywheel, external crank, water injection, harrop and obdtuner. 7. ufods B207r with standard internals,lightened flywheel and balancer delete, extrrnal trigger, Sachs clutch, 3" full Tullet, Siemens 630 injektors, Dutch ECU software Harrop charger Reaching 330 PS without water injektion Still searching for cams            8.Stig_1911    Vocky fettled B207,fully balaced bottom end, eagle rods,Wiseco pisteons,stage 2 zzp stage 2 turbo comps cams,supertec valvespirngs, balancer delete,arp bolts,TMS lighten flywheel, competiton clutch,2 intercoolers(side and roof) Using the 300 bhp dilbert kit as a base, probably dutch software.... goal 350+ bhp            

Put your plans on here so you can join forces with others who are buying the same parts. I'm getting some ZZP stage 2 SC cams of the wife and kids ( I hope ) did try to organise a group buy but got no response if ZZP

[techieboy]

Keep an eye on ZZP's Black Friday sale. I saved a few hundred dollars on the cams, injectors, pistons, valve springs and various other odds and sods last year.

 

No idea what, if anything, they're planning this year but last year they were doing big discounts on a fixed number of items and then the soon as they'd reached that number, they'd introduce a different discount on something else.

 

Did involve being up for the best part of 24 hours though and fighting to get an order in, before the Yanks snapped up all of the deals.

 

 

[smiley]

The dutch heads are at the porting specialist, which will not be ready before end of year. (it's not his dayjob)

With cams and injectors probably coming from black Friday @ZZP we should be sorted with all bits now, and start conversion early next year.

[CHILL Gone DUTCH]

Will tell the wife about Black Friday so she can wait up after all it's my Christmas present

[Graeme Lambert]

When exactly is Black Friday chaps? G
