Hey Mazworx can darton sleeves be bored to 92mm?

Yes it can. That is the max it can go to though.

can they use stock bore, i like 86mm!!!

Do you guys do dry sleeves?

Yes it can go 86mm

All SR's use the Darton dry sleeve kits

Just curious a block with darton sleeves installed can take how much power?

We run Darton Sleeves in our Drag S15 and it makes roughly 1400hp.

Sorry what I meant to say was, do you have sleeves that extent past the coolant jackets. Something larger than even the AEBS sleeves?

I guess its pointless though since you have proven the darton sleeves 1400whp capable.
