Will the intake manifoldmstill play as big a factor in performance when using a Ron's TB? Just thinking that since the fuel is injected close to the intake valve. The design of the intake may not be as critical. I hope 440JIM will share in opinion and any others using this system.

Yes.

You still need something that flows air well unless you go with forced induction. Adding fuel doesn't help if there is no air to help it burn. The amount of HP you are going to make is still going to be dependent on how much air flow you can get through the engine - In and Out.

I did a blow-thru, but never tried it N/A. It was nice to be able to change the jet pill at each cylinder to help get more even exhaust temps. And it did prevent pooling of fuel on the plenum floor.






I could probably be talked out of the unit, it has been sitting since I sold the Cuda in 2005.

My experience is bigger is better with injection as far runner size. The air coming in does not need to suspend the fuel so velocity doesn't have the same effect.

I don't have any special data on this, just my opinion.

IMO, the intake still matters, but maybe not as much.
You do want to flow as much air as the cylinder heads will allow.

I run my Ron's Flying Toilet on an Indy single plane intake(400-3 Dominator carb pad). But the -2 with the 4150 pad works fine too.

would 1 of you guys have a close up pics of the set up mounted ????? I just got my stuff and looking at diff. set ups on the front of the motor..

Not real close but all I have

Pump and mandrel.

Oops, that was my first drive mandrel that I made. I now have a modified moroso on there that also has the drive for my vacuu pump. Beep

Alky is more forgiving, so the benefits of a better intake will be somewhat less than gas and carbs. But total airflow and ram tuning will still be of benefit. Too restrictive with alky would IMHO be the worst situation to have. The alky does take up a bit more runner volume. My question is it worth it to spend over $1300 to go to a tunnelram. I would guess there might be 1/2 the gain of a carb setup, as I already have a huge (2100 cfm) throttle body.

I like the C-N-C Tunnel Ram,the c-n-c equals the runners which equals each cylinder.But is it worth the extra $$$ I'm not sure.
The set up on my old(not really old just have a Bigger one now)engine.

what's with the fuel lines being so low installed on the intake?

Thanks for your replies and pics. I have heard that nozzle placement is also critical as well as the angle of the nozzel. Any do's or dont's there I should be aware of?

I sent my sheet metal intake to Kinslers, with a hat, They flowed it, saying something about the mix makes different tq at differnt heigths. It's been a long time, so my memory isn't as sharp. It would take me a while to find the paper work. But here is how they set mine up. Maybe because my runner are longer, I don't know.

I'm not exactly sure but I think with methanol the closer to the intake valve, the more top end hp you'll make, and the further up the intake runner the more mid range hp. With other fuels the injector would be higher up the intake runner because that makes more power better mixing. Methanol takes up more volume
With injected sprint-car engines they will have injectors in the cylinder heads and the "intake manifold similar to yours" to get the best of both worlds.
