Working on a Group Buy for SFR Manifolds

This is for the 3rd gen, 4th gen & Coupe V6, & 6th Gen Maxima models. I told Tim I would try to get a good honest feel for what the community would want.

Intake Manifold ? SpeedForceRacing

I need at least 5 people between all those different cars for a $900 Shipped price tag on the GB to the lower 48s. Additional shipping charges apply to any other locations. If you want in, please post up and PM me so i can get a list together so we can get this officially going. If we can get 10 or more people, i am 90% positive i can get us a little better discount on the manifold.

the 4th gens & coupes have a special gasket needed that he will include that has been water Jetted out to specs. We are also able to use the after market FSTBs that we have since the size of the manifold is almost the exact external dimensions as the OEM plastic one.

Their dyno chart is a little hard to understand- not clearly labeled as to what the two lines represent. Is one a stock 4th gen? It says SE-R-
Anyway, basic intake facts- higher flowing intake- more power at high rpm, less at low rpm. Metal intake- more heat into the air, not best for power.
Without more reviews, my guess would be a good intake for racing, not so good for the street, and definitely not cheap. Nissan (and others) have spent a lot of time/money engineering the "split flow" systems to give BOTH good power at high rpm, and good power at low rpm.
I like vendors like Edelbrock, and Holley, and and Stillen, who will be clear about the intended use-

hmmm ive been creeping around the 4th gen altima forums for some mods for the 7th gen maxima..... hmmm ask him if the intake manifold would fit the 7th gen maxima because i know the new altima vq35de and 7th gen maxima manifold are both plastic and seem to be shaped the same

Looking at the dyno closely, it looks like it just adds power all the way across except for the middle part where it looks even.

Only thing about this dyno chart I have a problem with is, where the fuk is the torque curve!

I hate dyno charts that just show HP. I want to see the dips and gains etc. If this thing for some reason increase torque across the board, I will buy it.

This may be a shock to JKG, who appears to be massively ignorant of things technical- but a dyno never measures HP, and a chassis dyno doesn't measure torque, either. (an engine dyno DOES measure torque) But if you want to "see" a torque curve, you can get someone to help with complicated math..
HPx5252=torquexrpm.

Please stop posting, someone might actually read what you post and think what you are saying is fact, when it is all BS.

You know whats funny, you screwed up your formula. Who is an ignorant retard now.

Torque = (hp)(5252)/rpm.

Nice try though.

So this SFR probably won't make much more power than the 4th Gen intake manifold.

Apparently the 4th Gen intake manifold flows more than the 3rd Gen.

Those of us who got as far as high school algebra would know that the two equations are the same. You wrote the same equation I did, but you were so IGNORANT that you didn't know it. Thanks for proving my point- even though most of us didn't need more proof.

You still wrote it incorrectly because you are not solving for Torque. You just wrote the formula in general.

I know what you wrote, I wanted to proove my point - Ormand likes to talk out of his ass and thinks he knows everything.

All your posts are exactly the same, your just a waste of time.

Anyway, back in topic.

I wish someone found out the air flow numbers for the 3rd gen intake manifold and the 4th gen.

Can you cite this? I'm genuinely interested.

Its NOT so much the IM that flows more air, rather its the heads. The 4th gen heads are how it should have been done for the 3rd gen...Before anyone asks, NO the heads from the 4th gen will NOT fit the 3rd gen. BTW, I may also have to jump in on this if it happens.

I thought they would work? The JWT s1 and s2 cams work for the 4th gens. An Altima coupe did it already.

The heads must make a big difference because the WHP the 4th gen makes is like a modded 3rd gen.

Altima 3rd gen:

205-210 whp

SER

215-220 whp

4th gen:

233-240 WHP

Wont work. If they did I would have already scavenged a set and further increased the air flow with port and polishing. The 4th gen heads are awesome imho for what they are and what they are capable of. They really do make a BIG difference in whp.
