Debating Boss 302 Manifold

Hey all, I was hoping some of you could give me a little help. I'm very up in the air right now whether I want to order the Boss 302 manifold and Tune from American Muscle. Was hoping anybody who has 1 could hopefully tell me
About the power gains and if it was worth it. Thanks!

What are your gears? Current mods? Please go with a different tuner compared to bama

Personally, I think if you are not drag racing or road racing the car, save your money, you will need additional supporting mods to REALLY benefit from it.
Read this article, it could help you with your decision:

I will admit me and my boys do like to line them up a good amount. What other mods do you think I would need?

If my car did not rev so high I would swap back to the stock Mani.

Just got mine installed not to long ago and I love it. Minimal loss on the lowend torque and it starts hauling after 6000. Rev limiter was set to 8000 but I usually take it to 7500. Tuned by dasilva racing in toronto. 410/370 12.6 on 20" vossens and 275/35r20 trapping 116mph and 1.9 60ft. Need a better tire and smaller / lighter wheels

So many people talk about the torque loss, but to be honest, you dont miss it at all. If you want to be able to burn the rubber off your tires maybe, but I will trade the HP gains after 5500 any day. Feels like you put an afterburner on your engine compared to your stock intake. There has been so much banter online about torque loss and numbers in regards to the Boss IM, it has scared most people from doing the mod, yet most of the people that dis the install don't run it. The people who do run it like it.

Is it safe to spin the stock motor to 7.5k?

Is there any cases of people blowing the motor with the boss IM for overreving?

Yes to 7600 on the stock motor. The ring glands are weak, real weak also the stock oil pump gears can fail at high Rpms

American Muscle guys themselves told me that I could spend the money in much wiser areas if i was just daily driving. They said that if I am not track running it over 6500rpms really wont notice much at all. I decided I am going to do aluminum drive shaft instead and should see about same benefits but I have manual

The stock oil pump gears would be something I would worry about on a stock motor and the ring glands. Reving to 7800+, but if you bought it for performance. Goforit, if it breaks build it stronger

I only track it every one in a while so I won't be revving it that high all the time. But it would be fun to be able to rev to 7.5K at the track or at least every once in a while! Hmm..

Can't the stock internals handle around 600hp pretty safely?

Yes. Push it to 601 though, all bets are off. I plan on keeping a safety net at 595.

Name someone who's had trouble. We want to speak with them and demand explanations of the circumstances. We want them in on this thread, no more here say.

Only reason the boss is on my car is BC of my 8100 redline and spraying to 7800. Like i said its worth about 8-10hp tops over a stock manifold. And 20-25tq loss. I have 4.10's to make up for the loss I have down low
