Cammed Motors Specs + DYNO Graph Mandatory

Impressive all things considered on the above post.....

So a cam change is going to happen?

Naa, this one's done...
But more data for the memory bank & do better on the next one

Customer car

Engine - B18C7 (AUDM DC2 Type R Motor)
Displacement - 1797cc
Bore -81.00mm
Stroke - 87.2mm
CR -Standard - Approx 11.3:1 (Head overhaul + 0.6mm TODA head gasket)
Camshaft - TODA Racing Spec B (TODA valve train - cams, springs) Std retainers & std valves.
Camgear Settings - Intake 102.5deg LCA / Exhaust 102.5deg LCA (Vtec lobes)
Gearbox - OEM DC2 Type R
I/H/E - Mugen Airbox + Std throttle & manifold + TODA Header + 100Cel metal cat + SPOON N1 Exhaust.
ECU - Apexi Power FC


Above image shows TODA B B18C7 vs Skunk2 Pro 1 B18C2 (From post 541)
The TODA engine (blue line) makes peak power @ 8000rpm (rev limit 8600rpm) - 8500rpm shown on dyno sheet
The SK2 engine (red line) makes peak power @ 8600rpm (rev limit 8900rpm) - 8800rpm shown on dyno sheet
(Different gear ratios & wheels sizes account for approx 10km of speed difference vs RPM - both 4th gear)
B18C7 has ported head (previous method) / B18C2 has ported head (new method)
B18C7 torque charaterisic is typical of Toda 4-2-1 header & Spec B
B18C2 torque charaterisic is typical of Try Y header

B17C7 with new method head porting comming soon...
The aim is to pass 145kw @ the wheels with a std bottom end B18C7

wow total output power means jackall vs all that midrange but what if the c2 engine had similar compression not really fair against stock vtir comp

Peak power diff is only 1.2kw
The midrange is cams & header.
Sure, comp & gear ratio helps a little, but the C2 has better artwork.
More comp would help...
But the comparison was just stock bottom end.
140+ is doable with the port work with either B18.

Wow, very impressive figures.

Just one quick question and I feel like a bit of a retard asking, but how did you increase displacement from 1797cc to 1979cc with standard bore and stroke? I feel like I'm missing something really simple... -_-

LOL... The capacity is standard 1797cc...
looks like I mucked up capacity written with a dumb arse cut & paste that I didn't properly check.
I cut & paste the template from a previous post & the coppied the mistake.
Thanks though, I fixed it.

crashprash, what had you done to the car to see these gains? The parts you listed in each post seem to be the same.

[89lude]

port match the rbc and better tune maybe?

crashprash, what had you done to the car to see these gains? The parts you listed in each post seem to be the same.

Just the tune...
As time has past, I've learnt a lot more about getting the most out of the Haltech Platinum Pro since I 1st tuned Crash's car,
+ there was a new software update with a few extra nice functions so i asked him to come back in to get that done.
ECU Manager 1.10.2 over the 1.08 that was in it.
Anyway, my new tricks worked well.

Main advantage is better VTC response on the gear shift & transition to Vtec
Better knock control
& improved/revised injection timing

Tuning is one of those things where you get better & better the more you do it,
So though I was happy with the result when I 1st tuned Crash's car,
(shortly after the Haltech was released.)
To stay at the top of my game, I'm always open to learning & trying new things.
So, since it'd been a while since I'd seen his car, I was pretty sure I could now do better
Case in point, these results are proof of that.

Crashprash how does the car compare to before
