So last night spent the evening at work testing camshafts.
Car is a mk3 Ibiza cupra AYP, bored out 1mm oversize, wossner 8.5-1 pistons and PEC rods, relentless v3 exhaust manifold and 85k+ miles old stock KO4, SFS 3" tip, custom 3"downpipe and decat, 2.5" cat back, LCR injectors and MAF housing, AirTec fmic, WMI 50/50mix, cold side relocation kit and 008p and early half mb TT revo software, and finally as of last night a pair of AGN camshafts. I'll let the pictures do the talking but as for testing 3 runs before, camshafts changed on the dyno to try and keep accuracy and finally 3 after runs, no map tweaks.

69ECFC22-9EC0-4A78-8315-66890308EFEA-2476-0000025B2373CDE1_zps71be15e0.jpg

Results are night and day, gains between the lowest stock runs and lowest after runs show a peak gain of 18bhp and 35ft/lb and between the highest runs of the 3 runs gains of 18bhp and 32ft/lb

Wow, that's a great contribution to the 1.8t community.
My next mod I think. No losses elsewhere in the rev range to offset the gains also. What were the peak power figs, does it drive well, how much were the cams and how long did they take to fit.
Cheers.

i already asked, but do you have the part numbers :p

did you measure or compaired the cams before fitting them?

Sorry MexxT no part numbers on the cams other than the cam chain gears and they are the same numbers for all 20v cams, I believe chambers put up a list in a previous thread, AGN or ADR are the cams you need as for how it drives, it idles perfect and drives exactly the same apart form much more stronger! Totally transformed the car
 
inlet:

058109021 = ADR und AFY 8,78mm, 210°, 4° n.OT
058109021.B = APX, ANB, AEB,APU, AJL, AGU, AQA, ARZ, AJQ, APP, APY, AUL 7,67mm, 190°, 18° n.OT
058109021.K = ADR, APT, ARG, AVV 8,41mm, 202°, 16° n.OT
058109021.M = AWT, AUM, ARX, ARY, AUQ, AMK, BAM, AUL, APP 7,67mm, 190°, 18° n.OT
058109021.F = AGN, APG 8,41mm, 202°, 18° n. OT
058109021.E = AWB 8,6mm, 207°, 9° n.OT
058109021.D = ADR, AGN 8,41mm, 202°, 12° n. OT

exhaust:

058109022.B = AQA, ARZ, AJQ, APP, APY, AEB, APU, ANB, AJL, AWT, AGU, AUM, ARX, ARY, AUQ, AMK, BAM 9,3mm, 210°, 10° v.OT
058109022.C = ADR, AFY, APT, ARG, AVV 10,25mm, 210°, 8° v.OT
058109022.D = AGN, APG 10,4mm, 210°, 8° v.OT__________________

Forgot to also mention unless you have theexquiptment it's very hard to measure camshafts, I ran a digital vernier across all the cams and found the N/A ones to have a smaller diameter across the lobes, but it's total lift and duration is what matters

ok thanks.

well hunting for a set of AGN cams starts haha.
if i could make 10-18bhp more out of my k03 hybrid, than it would pass the 330-340 border :p

Are these cams able to take to the extra power etc? are they not made from a different material or something. Or are they exactly the same exept the size of the lobes etc giving higher and longer lift.

already found 3 engines haha.

but how did you change the cams on the dyno?
you need to remove the belt?

So that's with no tweaks to the map ? I imagine more must be available with vernier pulleys and a remap ?
