4.6 GT V8 Modified for road & track

[BlownMGB-V8]

Probably not out of line for a custom part. Might be out of reach for the Roadmaster though.

Regarding the TA heads, on the v8 Owners Forum a 5 liter Rover (NA) with TA heads was reported to put out 429 hp (engine dyno).

[302GT]

Clarification:
The 429 hp figure was extrapolated to the flywheel from a measurement at the wheels. Dyno graphs are not posted yet, will be in a few days.

Larry, I believe it is Mark's engine in this thread

[v8bloke]

Yes 429bhp at flywheel, 380bhp at wheels, 390ft lb torque.
Car is still at the rolling road as they have found a slight problem. intermittently one cylinder down ( number 6). They have diagnosed the injector as being at fault. Should have a replacement in a few days.
When I eventually collect the car I will upload the dyno sheet.

Well I haven't posted for a while.
 I have been having a miserable time with the new engine. To cut a long story short The mapper messed up big time running the engine very rich which resulted in smoke puffing out the exhaust after only a few hundred miles.
Had to have the cylinders honed with new rings mains and big ends.
On top of this the Engine will just not run properly. I have replaced everything and come to the conclusion that it must be the Canems ECU.
While the engine was being refreshed I had the car blown over and tidied up.






The car has been sent away to have a new Link G4 Extreme ecu fitted together with new loom. the tuning shop said it would take 2 to 3 weeks but has now been 10 weeks and still not done.
I'm feeling somewhat frustrated but hopefully I should see the car again soon and it should actually work.
Watch this space.

Can't wait for some more track video complete with more of those four wheel drifts like you were making in the first video !!!

[v8bloke]

Hi all, I haven't been on here for a while. For those that are interested, after a long long time of having running problems the mg is now sorted. 380bhp with 400 lb ft torque.
Here is the latest walk round showing new front valance/splitter and refreshed paint.
