I was up in joburg this the weekend before last and decided to go see my car again....
i dont know if i told you, but one of the shims decided to retire which caused head damage.... I sent up another head about 3 months ago and finally it was now complete... the previous head when i bought it had work done on it so it was ported around that... we got high power figures for sure but have improved drastically this time round.... the last head made at 0.35 bar, 176kw on the wheels, revving 7200....at 0.8bar we made over 200... With the new head and porting sorted out now, the car was ready for more action.... 0.8bar, 250kw on the wheels, 360nm.... i thought it was very good... The car is built for over 2 bar of pressure but the turbo we knew would max out before we had to boost it that much.... At 1.2bar we maxed the turbo out at 346kw on the wheels, 545nm of torque.....scary power... i asked him to boost it a bit more just to see the increments of power but it was not much.... 1.5bar, 365kw on the wheels, 588nm.... As you can see it was not worth putting the boost up as the turbo had done its job....Also, the effeciency of this motor is the key, cos its only revving 7200 which is less than standard... built for 8000, this motor has a lot more potential... i recon if i had to put a 3540 or something on it, i could get up to 450kw on the wheels.... Its for drift only so thats why the turbo is the size it is.... Guys, if you building these motors, look into match porting everything so the air moves through equally... yuo will see power gains... I know that there will be guys out there that will make more power, but lets see at what revs and boost they do that.... 😂 😂 😂
Later
