Is it really worth it?

[Henry Harris]

Having run-in the rebuilt engine and had an initial tuning, I took the car down to Torque Developments International at Lakeside. See this post as well - Re map in ESSEX. The improvement that they made is illustrated in this printout. There is still the matter of the secondary throttle not opening fully.

Scott, you are spot on. The set up at TDI appears very professional. The figures were taken at the hubs; wheels off. I thought the top hundreds was a bit weak for a 450. 220+ seems more acceptable. I am told I should get more when the second butterfly opens properly. I am going to have to get replacement Edelbrock carburretor springs from the States. Watch this space.

I managed to open it up this morning. It don't 'alf go. Like the proverbial clappers. Dare I say, more like my Griffith 500.

Now I am beginning to believe it has all been worthwhile.

Hopefully, these are the graphs that you are looking far. Interpretation for us poor amateurs would be nice.

The engine has a Kent Camshafts Fast Road Camshaft H218. I have a fuller list of the engine bay components and specifications. Send me a mail.

Adam, I had to be careful today. I nearly scared myself. The improvement has been so marked.

There are some useful technical tips on this topic. I am not sure whether I can do them justice.

Results from ATSpeed, which are calculated as being at the flywheel:



These two sets of figures leave me somewhat confused. I am content having spent the money that I do not wish to spend any more. I'll leave the readers to assess whether the whole rebuild over the past six years has been really worth it. Now, I will just enjoy the drive.

Excellent service from ATSpeed Racing. Alan even called me back to day to get my view on his efforts.
