Got our first Dyno results from a power run today, producing 492bhp at @5900 RPM, and it will run up to 6500 RPM but waiting to run it in a bit more. Our goal was 500bhp which seems very likely, but more importantly our hot cam has toned down the torque, we have lots of low down grunt, but as the revs rise we have lots of power.

First Run of LS on Engine Dyno
This is the first run of the LS – it will be first run in for a while before we do a power run.
LS Engine Dyno
Finished the spacer for the bellhousing to dyno and got the housing bolted to the dyno to confirm all was well, then partially loaded the van ready for sticking the engine in the back and off to emerald in the morning, got the engine connected up had to do a slight mod to my engine mounts to fit there fitting but nothing to serious, got the water system plumbed up ,sorted the thermo couples for inlet and outlet water temps connected, sorted some of the wiring but still some way to go on that front, tomorrow fuel etc. so coming along nicely hopefully go for a start late this week.
Cerbera Exhaust Manifold – Part 2
Got on well Friday made the third mounting for the nearside exhaust there seemed to be to much twist from the weight of the silencer with just the two, then started back on the offside got the manifold all tigged up, lobsterbacked the bend after the flexy down pipe, cut and dressed the exit bend and cut the straight pipe to length, just the welding on that and the mounts Monday then engine out and prepare for the dyno.

Water Injection complete
At last the water injection is all sorted with Richards help from DRL. I had to remove the board from the casing break the tinniest of links and solder a new link to give me the required volume of water injection, trouble was they assumed we had 100% drive to the injectors when on full throttle but that is not the case we use around 68%at full throttle so had to move to x1.5 on the scale hence the soldering but all good now, i also fitted the passengers seat tidied up the wiring to the Aquamist ECU and put it in conduit and refitted the dash so just the line locks to go.

TVR Chimaera – Triple Plate Clutch
Another day at the TVR mill got the trigger wheel for the speed sensor tig’ed up had to reduce the slots by half as the dash pro didn’t like the multi slot trigger on the prop shaft went a bit mad after 100mph so needed to get that done and repainted ready to go back on Monday Tuesday, also finally tightened up the sump bolts fitted the flywheel and sorted the clutch need to make a top hat bush for the release bearing carrier to fit the new 40mm i.d. bearing so coming along nicely.
TVR Triple Plate Clutch + Lightweight Flywheel
Clutch foot pressure will be about the same as standard the real advantage is the triple plates lots of surface area and terrific heat dissipation qualities, below is a pic of the new flywheel looks almost to good to use clutch itself will be here next week but been getting on with refitting the sump with new better quality crucifix seals and starting on the water injection install, i have run the pipe from boot to engine bay although not clipped up yet and sorted how all the wiring will connect and run the line lock turned up pm as well looks a nice unit.
