pistons?

[BLWNSRT]

I was the first and I would recommend them to anyone. Tony did his research on these:rock: 10k plus miles at 10lbs:elefant: :elefant: one word of advice get some extra dics for the ring grinder went thru 3:dontknow:

What compression ratio you running? I'm planning my build, my custom pulley that makes 6/7 + stinkers lower pulley.

Those look alot like my custom CP Racing pistons,my builder has had the best of luck with them and highly advised on using CP Racing,my builder had them done with a big upper ring landing,stronger forging,bigger wristpins and dropped down my compression ratio to 9:2:1,so far they are working perfectly:rock:

I stayed at 9.6-1. If I ever rebuild Im going 10.1 with the s/c

Yeah the ring lands on these are like 10x thicker than what the stockers are.

I did that on the ramcharger the stock 9.0 raised it to 9.8 + 12#boost.

Raising compression ratio and having 12 # of boost is a recipe for DETONATION!!!! gonna need to run good fuel. pump fuel might not be good enough .

With the right tune it can be done on 93. 9.8 is really not that high for the 318 or 360. I assuming its one of those

Would it not be better to lower compression , then add more boost than to raise compression and flirt with detonation and have to back off the boost?:dontknow:

I used to think that also but after a ton of research that was based on old school knowledge i.e carb era and the highest Ive seen on pump gas and s/c or turbo was 12.1/ w like 8 or 10lbs it was making crazy numbers (mustang of course) then a cuda or similar (body was shit but man that fugger ran) 14.1 10lbs boost (turbo) putting down over 1000hp on 107 oct. I know it not 93 but it is still gas

.040 over 360 with high flow R/T heads I run 91-94 with W/M Good fuel is the key. 7000km in 4yrs with lots of track time all out.

360 is very under rated motor. Ive seen 400mods blow before 360's.

I'm not asking for much out of my 10.... just 700rwhp and a good A/F ratio WOT

The whole purpose in lowering compression with FI is it drastically cuts back the heat in the engine which decreases detonation just like Huck is saying,I went with what my builder recomended,he has build 1000's more FI engines then I know about,I would rather have an engine thats going to last a long time with good strong HP,then a big HP engine with a short life span:rock: :burnout:

the biggest deal is the roe is not large enough to feed the v 10, so actually raising compression as the dawg did, actually helps the roe a bit, lowering the compression on a roe has not be yet proven to actually help any , no results as yet either with it helping a paxton

bone what happened to the first set of diamond pistons?

I gave them away after second engine rebuild.

 

[fastestbrickonearth]

oh i see

:aetsch: Now make an under drive pulley 2inch smaller thank stock:elefant: please

 

[JTS VENOM PERFORMANCE]

your wish is my command good sir, got a few things to take care of this week, and catch up on, but will get on it for ya sir

 

[Bone]

oh i see

There are some 20 piston ashtrays at homes of members of the forum! Both stock and Diamond.

I agree. After 12k with 9.5 to 1 off the shelve Diamonds my engine was burning 1 qt. of oil every 500 miles with 8 lbs. of boost. I'm now have custom Arias pistons. I'm now at 8.6 to 1 with 10 lbs. of boost. I won't be able to tune my motor till Feb. But with my safe break in tune I'm at 637 rwhp. My pistons are my machine shops custom blower piston sized for each cyclinder. I should be over 700 rwhp with a engine that will last longer than 12k miles.
