HAHA! Ok ok! Since the throttle bodies were Bada$$ I will probably do the M370 and the lower in the winter. Then TUNE in the spring

 

Has anyone dynoed all three(throttle bodies, upper and the lower manifolds) together and know how much they add?

 

Also I currently have the motordyne manifold. Is that the same thing what your ported upper is doing or will I see an additional increase in power with your ported upper? Sorry if this is a stupid question.

 

And I still have my stock manifold. Is it better if I send in my motordyne or better if I send in my stock one? Does it matter? I mean better as in will u see more gains with one vs the other ?

 

there you go! you're the only one dynoing correctly so your going to have the best back to back showings of everything! cant wait to see it!

 

i did but no base to show so it was pointless.

 

no the m370 is just a mani off the HR motor. we can port that or the VQHR mani! the BIG question is whats best??!! the m370 has better mid range but lower top end over the VQHR mani. the ported VQHR mani gets the mid range back and still has more top end. now the question is whats better? a ported m370 or a ported VQHR.

thats the big question if i had to guess though ported should be the same as the unported. M370 will have more mid range but less top end.

 

Will I be able to install the lower mani myself? Is that a diy? Biggest thing I ever did myself was the motordyne mani, and headers on my brothers cl. Is it hard and how long?

 

I smell a Lower Manifold DIY coming. Could help a lot of people in getting this mod done right.

 

yes! maybe? literally minutes!!! 15min i can have everything off.

you took the upper mani off so you're half way there. you have one bolt on the fuel line (let the car sit over night) and 4-6 on the fuel rails just holding them down. just pull it off with a towel handy as a little fuel will come out the line and if an injector pops out all the fuel in the rails will come out too. just pull the rails off and injectors as one and fuel will almost be zero! then the lower mani has 8 bolts just like the uppper mani had. just reverse and done!!

BIG FYI!!!!! be careful pulling the lower off. dirt sitting on top of the motor can drop down into the heads. before you go to reinstall the new lower, look into each cylider with a flash light and make sure you see and didnt drop any dirt or anything down there. if you do just get some tape on a stick or your finger etc and get it out of there.

its really really straight forward. just make sure you tighten everything to spec and in the proper order.

 

i can right up a DIY When I get my throttle bodies in! then again the only difference is most of the OEM hoses have been re-routed for me since I have the M370 on the car.

 

I can port that m370 and port match the TB's!

I could do...

Ported HR upper
Ported HR lower
Ported m370 upper
Ported VQHR upper
Ported VQHR lower
And CNC TB's for all are the same.

 

yeah don't get me started! the throttle bodies ship out yet?

 

Yes, they are getting done now. Sorry for the delay, all the sets I bought were shipped out and I was waiting on some returns. So this doesn't happen again I bought 3 more sets.

 

So I have my stock upper sitting around. Could I send that out awhile? And do you have a website or how does this all work out if I decide to do it ?
