Anyone heard of using HR buckets on a DE (along with a cam job, ect)? I heard from a credible source they can provide cheap gains by greatly lowering friction.

 

buckets? same as the lifters?

 

Iirc cosworth recommends them since the come coated with a special lubricant.

 

mine should be here tomorrow hopefully.

without cams and the buckets my hp on RT's dynojet is 265hp/232tq.

 

so what are you guys talking about? the part that the cam lobes are in contact with?

 

yes they are DLC coated to reduce friction up to 40% 4 buckets per cylinder total of 24. They started using the coating in the HR engines.

We shall see what happens the car is getting JWT S1 cams with the HR buckets car should be done by the end of the month.

Dyno is 2nd week of Nov at RT Tuning hoping for 280-300 with the cams and buckets. Usually gains from cams are around 10-20HP.

I will then do a same day before and after dyno of stepped 1.75-1.875 PPE LTH for the DE. Here is a pic of the driver's side from their facebook page. http://www.facebook.com/pages/PPE-En...LC/66546877151

 

maybe i should get some before i torque my cams down...
are the HR buckets expensive?

 

$20-$30 per bucket. Did you read up on DLC coating?

wow, kinda pricey. i am gonna call my head guy and ask him about those someday this week. i am guessing the thickness of the dlc coating might affect valve operation though. and it says 25% less friction if the whole engine has the coating, so probably wont be a ton if you just add the lifters/buckets

 

Do like those long tubes! What's the price like?

 

They are longtubes they are cheaper than FI. I will be the 1st for a DE. I sent them my stock manifolds and cats to get the jigs right for us DE folks.

Price will be the same as their 370z LT headers on their website. I should have them this weekend or next week they have to get thermal coated.

The headers will be stepped similar to SG, but for about 1k less. I hope they perform almost the same as theirs.

 

Nice! Some halfway decently priced quality long tubes. At least let's hope they are high quality

 

they make headers for other cars also. I know they have headers for the IS-F. I think they are mainly known for making headers for toyota/lexus.

 

I'll take plenty of pics when I receive them. When do you predict that your engine will be done?

 

when you say done, do you mean assembled? or in the car and tuned?
im more interesed in the buckets for now, cause my next step is to torque down the cams which i need to hold off on if i will be getting HR buckets.

 

In the car running in 2 weeks. Tune 2nd week of Nov tune for cams 1st then install and tune LTH same day.

 

wow, im jealous, im a weekend warrior, quite a bit slower

 

you have any pics of the hr buckets?

 

Will that also be the reason why HR engines run a lot hotter than DE?? Just wondering...

 

Why are you tuning it twice?
