Has anyone installed a ported Super Ram on a stock L98?

Looking at buying one, but it's been gasket matched to Felpro 1205 gaskets.

Any help would be appreciated!

 

I have such a set-up. When I refer to stock.........I mean stock heads and cam. I picked up about .2 in the 1/4 which may relate and equate to about a 20hp gain. I also had a custom chip burned to my mods at the same time however.

 

Unless you're having your L98 HEAVILY ported to match, or are getting aftermarket 195cc heads, you're going to have a mismatch (ie, a step) at the intake runner ports vs. the cylinder head runner ports. The interruption in airflow from a 1204 vs. 1205 could translate to a hp reduction in the neighborhood of -20chp.

It doesn't make sense to only do the intake mod. I say this because if you're going to remove the intake, you're only a few steps from removing the cam. Why stop? You'll desperately need much better flowing heads w/good velocity (heads are the HEART of making power on an N/A engine) + a higher duration/lift cam (recommend the LPE 219/219), and absolutely open up the exhaust with long tube headers + high flow main cat + and dump the stock mufllers with some other configuration at the rear, of your choice.

Get all the parts first, and have the whole shibang done at one time.....saves alot of time, labor $$ bigtime, and/or patience if you're doing it yourself. Then you'll be somehere in the 375-400chp range (or a little more) and alot happier because of it

 

Actually... what I meant was - The lower end and heads are stock at this point.

I have long tube headers, Corsa LT1 exhaust system, 52mm TB, Accell 300+ Ignition & coil, AFPR, Underdrive pullies, all smog stuff has been removed, no cats - I was told when i bough the car that it had an aftermarket cam - I have no idea of what the specs are..

I figured the SR would be a great addition to what I have now, but the port work on the intake bothers me a little...

So I guess my question is - would the "step" really hurt performance?

Should I look for an un-ported intake and later have the heads and intake ported at the same time?

 

Wasting time and money in my opinon. Only way to get noticeable hp/tq gains on the l98 is cam/heads/headers or stroke it to 383/396 package.

 

also add the SR intake into this mix

 

Ok... Am I wasting money or not??

Looks like both of ou have a SR intake...

Are you saying the SR is a waste of money? Or are you saying to build a 383/396 with a stock intake??? Or build a 383/396 with a SR??

The way I see it... If I have a SR intake on the car now with the mods I have - it will make it run better - Right? And if I build a stroker motor, I'll have a good induction system.. So buying a SR now is NOT a waste of money?

All I really want to know is - Is the SR a good intake?

I passed on the ported SR and now looking at a "new" SR

Am I headed in the right direction?

 

I cant answer about the step but I can see the airflow issues, the turbulence generated I am sure would have a negative effect on the intake port velocity. I have the Superram on my ZZ4 which is basically an LT1/4 rotating assembly in an L98 block with 113 heads. My superram is siamesed and heavily ported, but not gasketmatched as I did not put the manifold on, a buddy of mine did it for my girlfriend to suprise me. I guess she really didn't want me wrenching on the car, wanted me spending time with her! lolol But anyway, by SOP I feel a great difference from the SR compared to the stock TPI. I dont race as there is not a local track, and I dont have a local dyno either. But I do understand what they are saying about having to pull your heads to do it, might as well keep going. If you are not sure about your cam specs, i would consider the 219. I have the hotcam and want more.

ps. If you ARE for sure going larger cubes, go for it! It will only help now, and will definitely benefit greatly later!

 

You didn't mention going 383/396 in the future in your original post.

The SR is a good intake. I have one my 85 383ci engine. The stock intake on a 383/396 is not the way to go. You need more air which the stock intake system can't provide, ported or unported.

 

I'm running a stock unported SuperRam with stock cam, 1.6 roller rockers, headers, exhaust, 180 tstat, 52mm TB, cold air induction, and air pump eliminator plus the usual free mods.

When I put the SR on I had stock exhaust manifolds and stock rockers. I didn't feel a big difference (except the 4500rpm "wall" had gone and it revved harder). After some time the car dynoed about 20hp better than its previous run (stock chip).

Putting the 1.6 rockers made the biggest difference for me (after the headers were installed).

Not knowing what your cam specs are makes it a bit of an unknown but assuming your cam was close to stock I would recommend waiting until you are ready to do the cam as well. For all the work involved in the 1st install (it gets easier after the first time) I would wait until I was ready to do heads and cam at the same time if I had to do it over again myself (especially given how much you are investing in the SR in the first place). Right now my car goes better than it ever has but I know my cam is holding me back in a big way.

I have a 219 cam on order now and am looking forward to installing it and doing the chip and some headwork at the same time.

Short version - you will likely notice some gains just by putting the SR on but they are nothing compared to what you will get if it is matched with the correct cam along with headwork and programming.

Hope this helps.

 

What I believe they are trying to tell you is that it is having a compatible combination that works. Chosing that SR OR MINIRAM will not be as effective w/out other changes. A ported SR, what was it matched to? The comment refering to 195cc heads is a comb. that would require little if any port match (not to mention flow). and flow better than a stock L98 113 head, then comes the cam. Stock probably isnt going to benifit that much w/ this combo, so selection to match, a combination of upper end parts would be the way to go.
