mapping question
right then., i was wondering if i could squeze anymore power out of my sti type ra. here is a link to the spec of the engine. its peaking at 1.8 bar and tailing of to 1.6 at 6,500 rpm. running octane booster with v-power
power graph. http://i302.photobucket.com/albums/n...Zendynorun.jpg Engine: Engine built 10K miles ago to the following spec 2.0 litre Closed Deck Block with oil squirters, decked and honed to correct clearances for high boost/power applications, block converted to phase 2 thrust bearing location. Oil pump stripped, checked and shimmed for 7BAR oil pressure 8.3:1 compression ratio STi9 cross drilled and nitrided crank STi8 forged pistons and rings STi9 Rods with rod bolts STi9 steel head gaskets ACL race main and big end bearings STi5 heads freshly decked and valve seats cut, correct STi5 cams and valve springs (all individually pressure checked) etc, clearances shimmed correctly 16 x new Supertech stainless valves, new valve stem seals TD05 Big 16G FE turbo running at 1.8BAR peak, 1.6BAR at top end EcuTek Mapped by Bob Rawle showing 338BHP, 347Lbft on the Zen Performance RR last month, shows aprox 10BHP/Lbft more on the road using Delta Dash AP racing organic clutch, feels like stock with no judder unlike some alternatives Exedy billet flywheel Ported and wrapped stock headers with slip jointed magnex up-pipe (small bore version ideal for spool and 400BHP power levels) Scoobymania 3” stainless downpipe and resonator centre with bespoke quieter than usual 3” system backbox PFR7B plugs High flow panel filter Group N fully baffled sump Oil breather system with return to sump feed The engine is specced for over 400BHP with a turbo and injector swap and remap, it’s currently setup for daily use and is a very quick cross-country drive with lots of lag free torque.

Not a mapping issue IMHO, needs a better intercooler.
|
might change to a sti8 intercooler. or front mount. would it need remapping for a fmic?
|
right then. Going to change to a top mount I think. Then maybe a fmic in the summer. Will the car need mapping after a fmic install?
|
Just ask John ;):D he has had 2 of these (this one being his last one :))
Tony:) |
I spoke to john. Might be buying his topmount. He said if I fit the sti 8 intercooler it will run more power. Will be better on them warmer days. Not in any rush to fit one. As it's very fast now. Just I was getting about same power with my old car on less boost. But that did have a fmic. It's just the bug I have got, where I'm always wanting more power.

How come the bhp/ft-lb plots do not cross at the usual 5400rpm..?
:wonder: |
It should be 5252rpm Jas, and would be if the scales on the left and right of the page were the same.

Fit the STi8 TMIC and start saving for a better turbo, MD321H will spool very similarly but pull all the way to 8K and make around 400bhp.

Ah, hadn't spotted that..:freak3: I knew 5400 weren't right (thought it was 5300 something :rolleyes: ) but couldn't be bothered to look it up..:lol1: :thumb: |
