Hi en Sirazul and team,
Currently my car have these items, 4g93p, oversize pistone, half race cams (272/288 ??), std t.body with std. intake manifold, 4-2-1 xtractor with 2.2 inch straight piping (no muffler), std crank with balanced internals, adj. pulleys, lightweight crank pulley, lightweight flywheel, SAFC 2, Mivec ratios.
So the problem went like this, my car develop strong power at 3500-6500rpm only, and after that it was nothing (flat all the way). So i was looking for that high end power since my cutoff is set at 8000rpm. Fyi ive already play on my exhaust piping size lengths , cam timings etc which is still the same. Meaning that when i upped the diameter of my pipings, i lose my torque (same with using oversize t.body before) which i lose torque as well. So in driving, i will get the strong power everytime i upped gear, but it will went flat after that. The engine will still revs to the cutoff but it is totally flat.
So my target is to maintain that strong midrange with a power available on the high rpm too. Target powerband is from 4000-7500rpm at least. Can your custom tuned intake manifold give the power i needed ? What do u think.
