I was going to just get the edelbrock setup but then i seen that i can get slp runners from thunderracing and an accel superram base from jegs for the same price as the edelbrock setup from summit. My question is which one flows the best out of the box and which can be ported the most. Also will the superram base even work with slp runners or are they strickly for superram?

 

Neither.

TPIS Base. AS&M Runners. Best flowing combo for a readily available LTR setup. However, I wouldn't bother with either. Get a Holley StealthRam. Best bang for the buck in terms of horsepower and performance per dollar.

i forgot to put no stealthram or superram i live in a strict emissions area and i dont see the point of bolting on a hsr and losing alot of torque to gain horsepower in a area my engine well hardly rev too. This is my daily driver i love the torque tpi has so i want a ltr setup that will give me more hp but not sacrafise torque. I hear all a big mouth base is an edelbrock with cleaned up castings and from what i hear as&m runners cant be ported and siamesed runners will outflow them. I just wanna hear which flows better between the setups i listed. trying to go for the cheapest too big mouth + as&m runners= $840 over 120 more then the other setups i dont see the point in paying that much more for something you cant siamese.

 

I believe the Superram is emissions legal unless you had another reason for not wanting it.

 

When i was talking about emissions i was focusing towards stealthram. i dont want superram cost way to much and i dont feel like loosing low end torque. If this were a race car with a 383 big cam and heads i wouldnt even bother with fi id go carb but this is my street car. anybody kno which is better between the setup i first posted??

 

Ive seen guys compare the Superram and really havent lost much TQ so Im not sure what you mean. The LTR will add up quick and the expense of the Superram wont be far off. If you look you can get a used Superram fairly cheap so your still looking at the cost of the base. There is a member here running a ported Superram and they dynoed it at 500hp and the torque is still through the roof almost hitting an upwards of 570 lbs of torque something a LTR setup will never do even fully ported.

 

Even though there are a lot of benefits to go with a stealthram or superram, the gains will not be worth it unless the engine is highly modded(heads, cam). And plus, maybe he doesn't want to get into those right now....the stealthram I know is not 100% bolt on either. I would say stick with the matched edelbrock set.....that way everything already comes set up to match, and I have heard good things about it.

 

If you do a search you can see guys gaining quite a bit from just a LTR to a Superram switch.

 

well i understand that superram and stealthram are way better but my car will only be revved to 5500 i like the ltr setup i dont want this to become a superram and stealthram are better. my car will see the track once a month and it is my daily driver. I just want to kno what ltr setup is better edelbrock or the accel/slp setup.

 

Well, the TPI setup is only really good for 4500-5000 rpms. The superram is still good for lots of torque and will allow you to make horsepower too 5500 rpms.

But if you wants lots of torque the TPIS base is a ported Edelbrock base and TPIS runners are big and long too keep your torque peak low. Siamesed runners raise the torque peak up 500 rpms or so because they effectively shorten the runner length a couple inchs.

 

I bought the Edelbrock set up. I'm pretty happy with it. Plus it looks good. Its not a plain looking TPI set up. Make sure you get a ported plenum to go with your intake and runner set up.

 

You can use whatever intake you desire but it kills me the way guys have to work so hard to make an LTR work. It almost feels limited to what intakes are actually smog legal so it does suck. And wtf is up with BBK they have been advertising a new tpi intake forever now.

 

yeah, ive heard about the tpi intake bbk is making but never seen anything from bbk about it do you got a link that would be great. I understand what your saying about superram but i have my heart set on 12.9's with ltr along with trick flow 175's, and a lt4 hot cam and 3.42's and just about every bolt on (like rr, afpr, pulleys)

 

If you go to the BBK homepage it says new GM TPI intake coming soon. The problem is it has said that for 2 years now.

 

The edelbrock High-flo base is the same as the TPIS base. Edelbrock makes the base for TPIS , but TPIS just cleans it up alittle and renames it. The ACCEL,Edelbrock and TPIS base all have the exact same port sizes. So get the cheapest one. As far as runners go the AS&M and TPIS Larger Tube runners are the exact same, both made by AS&M. If you are looking to stay with the LTR setup I would go with the AS&M runners. They are cheaper then the TPIS runners which are the same,but in stock form out flow the SLP,ACCEL, and EDELBROCK runners. I was going to go that path but decided to go with the SuperRam because the price was only a bit more and it made more power then any of the LTR set ups. It is 50 state legal.

 

You can get in the 12.9's with a LTR setup. I've run 12.5's and a best of 12.47 with a ported Edelbrock manifold and ported SLP runners on top of TF 195 heads, LT4 HOT cam, Hooker 2055 headers, 3.42's, etc. See:

IROC

for all of my mods. I just installed a Stealth Ram last month in the quest for more top-end power and hopefully 11.9's this fall.

 

i see you race at mir i live right by there and go there all the time. you went with bigger heads and a 355 to pull off the 12.4's im hopin to get away with smaller heads and my stock 350 block to get 12.9's.

 

I usually go to Capitol Raceway since it's a lot closer. I used to go up to 75/80 before it closed. I've been up to Cecil County a few times since I have friends up there. If I had a higher-stall converter, I would've been in the low 12's, but that's another several hundred dollars I don't have...

 

Agree with Greg 100% on this one I went EASY 12.5's with a LTR setup (TPIS base and AS&M runners). LTR setups are underrated. I'm 100% positive I could have got my LTR setup to run 12.3's. I'm 90% sure it would have went 12.2's. I just never invested the time in it and I really wish I would have. The 12.5's was completely untuned and was my first pass EVER down a track.
