Its going in this coming week fella

On a stock engine you'll probably get more power with 421's but the headline costs will be more.
You wont find many on here who will recommend you Pipers with them being re-grinds. I can only praise them as my motor ran very well with them.

I can get a set of 2nd hand 421's for the same price as the piper re-grinds.

I think I may have just decided

I forgot rule #1 of modification - Never quote power figures lol

 

[Fred@BTM]

correct!

 

[Ad172UK]

lol

Do 421's usually make more or less power than 428's?

That questions a safer bet :rasp:

 

[Fred@BTM]

pass i haven't used any in a long time, i do recall either them or the 423's being peaky as f**k

 

[sideways danny]

421s give similar peak numbers to 428s, but with a much better midrange. FAR less peaky

I'll go with the 421's i think.

Will probably make the car easier to sell on too.
