and Songman's also had rods, could run higher boost as a cosequence, (dont know if it does, but torque comes from somewhere) and maybe not insignificantly a Dahlback inlet manifold also.
not a 100% comparison of specs.
my old motor did suffer blowby, judging by oil breather huffing and a puffing - lol - 340bhp I think just before it was retired for the new 1900 motor.
I have no other Dyno info than that which Jabba did when they worked on my car - sorry I can`t be of more
help
I`ve never felt the need to dyno the car again - my project was for road use, not track, strip or indeed the be king of the Dyno shootout - and as the car goes extremely well on the road
- i`ve got no complaints at all
I`ve done 30000 road miles with the car since the work was done last December, and have encountered most of the sporting `competition` from rival car manufacturers with supposedly standard power outputs of 350/400 BHP - and no doubt Jabba`s 370 BHP has proved somewhat more `muscular`
than the opposition`s, when called to account.
As far as dyno charts and power figures go, the car most definitely has freed up with the miles since the rebuild and feels now that it has more power than it had when Michael had it on the dyno
I have had problems - the first turbo`s bearings failed at 17000 miles - due to my fitting a `faulty `DV valve
say no more!!! - I`ve done 13000 miles on the latest one without incident, so the jurys still out!
I certainly have never had problems with either manifold or exhaust housing - the highest EGT i`ve seen is 875degC downstream of the turbo
I am without doubt running right on the limit of the VF34/20, and thus I only use the extremes of the car`s potential as an occasional `overboost` facility - I normally control the maximum boost at 1.6 bar by setting back the boost control
I checked last night the boost figures on the road at max and with inlet temps around 15dec C the car gave 1.82 bar at 4000 - 1.54bar at 6000 - 1.44 bar at 7000 - and I think about 1.34 bar at 7500 - the run being done n 4th gear
In practical terms the car will just hold traction and no more on a dry road at 4000 rpm in 4th even with a diff and sticky rubber fitted
In general performance terms, it will do 80-100mph in 4th in 2.4seconds - it will run off the clock in under a mile from a standing start and will show an easy 160mph without effort on the GPS at about 6500rpm in 6th - it still pulls very well past that. The most i`ve seen is 169mph on the GPS at around 7000rpm
I`ve no doubt that the new turbos will be even better results than mine, but, in truth an extra 20 bhp means little to me[about 3mph at the to end] so I will take a lot of convincing to change for change sake
The car has been a huge success as far as 1`m concerned - it`s the fastest general purpose vehicle i`ve ever owned - so well done Jabba
The icing on the cake is that I get all this performance and 28mpg into the bargin
