What lifters are all you solid guys running? what style? what diameter?

 

What heads? The lifters partly play into that especially if you run head that want offset lifters.

Either way I like to stick with the Comp stuff. That's obvious from most of my posts though.

I'm actually stuck at a crossroad now... I can't decide on a solid or hydraulic setup. Basically I've got cam recommendations from Cam Motion for both setups and I've just got to decide one way or the other. Frankly, I (and others) think the HYD setup is very small for what I want to do. Its 214 in. 210 ex. @ 0.050. Lift is mid .500's, LSA 115. The solid is ~225 in. 220 ex @ 0.050. Lift is mid .500's, LSA 115.

I intend to make all of 600 rwhp will keeping it as streetable as possible. This is a street setup!! It hasn't been to the track as of yet and I seriously doubt it will see many track days. Shift points are to be at or below 6500.

For these specs and what i'm using it for, what would you do? Solid or Hyd?

As long as you don't mind a small amount of maintenance (check lash) there is no reason to leave HP and driveability on the table with a solid.

I'm assuming you are talking forced induction with 600rwhp and a hydraulic?

 

Jesse, as Bobby asked...please clarify if you are talking about a blower setup. I assume you are.

If you are talking about a forced induction application, I would strongly recommend staying with a hyd roller. You are not going to gain much with a solid over hyd in a blown application. However, plan on spending alot of extra money. To me, the extra 25hp or so is not worth $1000+....only in a "race" configuration. On top of that, anything over ~500rw is not real usable on the street. 600rw is easy to make with a street hyd roller car as many guys have.....even with small little S-trims. Save the money from the solid setup and buy a bigger blower if you want more....you will be way ahead that way.

However, solid roller in NA applications is a great way to go IMO.

 

Sorry... This is a turbo application. T-76.

Still think I should stay HYD? Also, is there any problem that I'll collapse a lifter?

^^^home made twin kit on a build 380" windsor motor with good stuff inside

motor can make over 1000hp but when it was dynoed it had on little tiny .58a/r exhaust housings

it has a FLAT TAPPET IN IT

Stay hydraulic, cheaper and easier to maintain

**EDIT**

DOH! i took the pics of the stang off my site, anyway the above should convey what i'm trying to point out

Another one of my friend's has a 454"bbc with twin 70s with log manifolds and a flat tappet in it, on 10psi in a 4000lb car it went 145mph with a bad converter

 

It really all depends on the user and what you don't mind doing.

A maintenance free valvetrain that is going to be kept under 6200 rpm is the perfect candidate for a hydraulic. The proper sized turbo on a healthy small block for street driving will make more usuable hp than you can handle as well.

At the same time, I like solid rollers and what they have to offer, even on forced inducted motors. I won't go in to it too much but thats just my opinion. I think it ultimately depends on the end user and what they want to do.

 

Agreed, even in a blower motor (if it does nothing but race) I'd go solid but for a street driven car that doesn't need to turn lots of revs, a hydraulic will make all the power you need.
I don't think the camshaft pick is too small either but I don't get the whole "reverse split" thing on a blower motor that needs even more time to get rid of more exhaust?
Any ideas on that theory??

Be happy, go hydraulic for what you're doing.

Mindgame,

I'm using a turbo, not a blower. I thought it was common to use a reverse split for turbo applications. Is it not?

Jesse

 

Yeah, most are same/same or reverse split. I wasn't paying attention as most of the questions in here are about blower motors. I cruised through the thread too quick. My bad and sorry for the confusion.

Would you PLEASE email me any and all information you can about this car! It sounds similar to a progect I had in mind

 

car is for sale if you are interested...turn key package

here are some pics of it. Rough on the outside/inside but it's built to go fast

hahahhahah!!

please note the use of the pepsi can in picture 31... its the coolant overflow tank

 

Jim,

Tom is selling his car? ?
