The dyno figures are with stock HS6 carbs from a B18, with only the needles changed.

The idea here is not an ultra HP engine, just a really simple way to substantially upgrade the performance of a daily driver. We really wanted to make as few changes from stock as possible. As it is, it is a cam, ported head and exhaust system package that that bolts on to a stock B20 bottom end and produces 150 HP along with as much low and midrange power and torque as possible. To some extent I am publishing these figures as an answer to those who think that you can't get significant top end HP increases without losing low end torque. Would love to see dyno figures from some of those engines, including those that are bored and stroked, as discussed in prior threads, to see if they are really getting any better low and midrange power and torque with their " sacrifice top end power to get better low end torque " philosophy.

I must confess to not having done a lot of experimenting with different SU carbs,
and no work prior to this on the dyno, so your advice is highly appreciated. We wil continue to develope this setup for those who are more interested in top end power and may need to change carbs. Probably at least another 5 HP is available with the stock SUs with better tuning of the top end with different needles. I expect different carbs and some other minor changes could get us 10 HP more but will not know until we do the testing. Will be interesting to see what happens.
