good to hear, when she off?

Got my car back! Happy about that. Conversion of quad throttle bodies is a success so far. Car pulled an extra 9kws which for NA is a very decent jump and much more than I expected. Peak power jumped 700 rpm to 6500rpm and car pulls all the way to 7000rpm cleanly.

The 9kw extra is not from the same dyno as my Pinto Powerboard figure but the last place that tuned the car with Sierra EFI setup so it's a proper before and after figure.

Right now I need to go get it ready for Classic Ford Dyno day (needs alot more work)

Well done Rhys, you'll have to get some pics up of the finsihed product..

Well done mate.
See ya at dyno day tomorrow.

Bit of an essay....

Ok got all my dyno sheets out since owning car, rebuilding motor, before after and Sierra EFI and now quad throttle bodies.

The first dyno tune I had of it was back in 2001 where it nearly snapped the rollers at 56rwkws this was with same cam it's running now (Kent FR32) and a 38DGAS carb

Then in 2003, it maganaged 58rwkws same engine combo as above, with carb serviced.

Then car was pulled off the road for too long and went through a rebuild. At this time I rebuilt motor and put a few more goodies in it with Sierra EFI and a Haltech fuel only computer, first dyno tune it pulled 85.9rwkws at 164km/h this was in the start of 2006. As a result of that, the car hammered but broke down that day and without going into it the car will never go back to that dyno.

A month later I took it to Boostworx, and it pulled only 74.2rwkws at 120km/h this was a fair way down on the above, the 43degree day may have had some impact but later that same year and the last time I had Sierra EFI setup dyno tuned it gave a reading of 75.3rwkws with an adjusted tune. So it shows a bit of difference bewteen dynos.

So here I am thinking what can I do next I was over the Sierra setup already and wanted to try something different, went with the Suzuki throttle bodies and at the same dyno with new setup, this time with a new computer it pulled 84.3rwkws with a 90-95% tune as the car needs bit more work before tune can be completed. So I guess out of all that the only real way to say what the mods have done it the 75.3 vs 84.3 figures. I got the car back at midday Friday and had it get in a roadworthy state for KPM dyno day the next morning

Then yesterday at KPM's dyno the car got 108.3rwhp which is about 80.8rwkws?

So for those wondering, there it all is. I walked away with some things to improve on yesterday. First up is to fix the vacuum leaks in the manifold because I had a thread tapped into the top of each port incase I needed a vacuum port, all of these are leaking, and my throttle linkage isnt quite right because the t/b's are spaced to suit manifold so the throttles arn't balanced perfectly.
Then it's time for some more tuning and a fiddle with cam timing as it's never been touched via the adjustable wheel. Then once thats done I'd like to leave it and enjoy it.

Great job Rhys!

So a noticable change to throttle bodies compared to the Sierra EFI(throttle response etc)?

What was the torque curve like compared to previous set-up?

Car looks fantastic Rhys, a real credit to you. Car must sound great with the quad throttles on it now, hope you get the minor issues sorted so you can enjoy it
