525sc intercooled
 

Has anyone intercooled their 525sc?
Thinking about doing it. Have been told I can run 8lb boost w/intercooler's. What do you think? 100hp+ per mtr gain. :D

Re: 525sc intercooled
 

Not worth spinning it up that hot(14,000rpm's) to just take the heat back out....change them out for 8-71's.

Re: 525sc intercooled
 

I did it,no problems so far!

Re: 525sc intercooled
 

I would say more like 50-60hp. You can run 7.5# w/o the cooler without any problems. Won't make as much HP, but it can be done. I have done it for almost 250hrs.

Nice looking ride JJONES :drink:

Re: 525sc intercooled
 

Griff,
You think only 50-60hp gain w/chiller and larger pully?
I thought you may get 50 w/chiller alone...

Had a pair for six years with the chillers and the pulley upgrade. Ran at 7 -7.5 lbs. and were 100% trouble free. They made over 600 hp, only thing I did was to change oil ever 20 -25 hrs and plugs. Often wish I still had them. They are less stressed at the higher boost intercooled than they are stock without the intercoolers.

Thanks Ragged. 600hp would get me close to the 100mph mark! :D

DRIPPINWETII,THANKS! :evilb:

Re: 525sc intercooled
 

Same here....
I say its still better to do the larger blower....not that the other way won't work for ya.
When I had my 525's rebuilt we went with roller cams and 6.5psi pulleys without chillers, they made 580HP on the dyno.
I ran the pisss out them.

Re: 525sc intercooled
 

Thanks for the input everyone. I think I will be adding Chillers and boost this fall!
:D

Hey Guys,
I have a friend running a 525SC in a 29' Fountain.
He is considering a cam upgrade as well as raising the boost.
Which roller cam would you recommend?
Thanks,

Crane xxx731 is what i replaced mine with.

Re: 525sc intercooled
 

I have the same cam in mine.

Re: 525sc intercooled
 

Thanks for the cam suggestions...
What type of power increase can be expected with the roller cam and boost upgrades?

Re: 525sc intercooled
 

What timing are you running? Are you still at or near 35?

Where the hell have you been Jamie??? Have you been on the Lake?

Hey Neil,
I have tried to get together with you guys but seems we end up in diff locations.
Didn't go out Sat but was in Niquett bay Sunday.
Now I know where Deep bay is I can find you! We definately have to hook up at some point this year.

We will have a big tie-up for the Air show this Sat. Friend is bringing his boat inside the Breakwater on Friday. My plan is to get there around 9am and tie up with him.
Most my friends have cruisers and smaller boats. No go-fast's :rolleyes: . Maybe Sunday we will see you guys?
Jamie
