The piping also greatly affects the pressure drop through the FMIC that also needs to be taken into consideration. If you notice with the piping setup of ole whore's FMIC, The piping from the turbo to the IC is smaller than the piping to the throttle body. Why do you think that is?? That would actually affect the amount of lag produced.
Depending on the piping you use, the FMIC would still flow greater amounts of colder air than the TMIC with slightly more lag.
I am not disputing the lag.
Consider this: TMIC flowing cold air but quickly reaches max flow capacity. FMIC flowing air of the same temperature, but does not reach max flow capacity as fast with a 1 psi drop in pressure. The top end flow would be much better. Which one you think works out better even with the pressure drop? |
- pressure drop with TMIC = 0
- The pipe diameter is reduced to increase flow rate under a specific pressure in an effort to reduce lag. Did you know that increasing and decreasing the diameter of a pipe along a path of flow of a fluid at high velocity, creates turbulent flow? Laminar flow is what is desired, which is why constant diameter is preferred. Momentum is also affected as mass of air per unit volume suddenly changes. (I did this stuff in school  ).
Where did you get the term "max flow capacity?" An intercooler is like a box-shaped pipe with little radiators all over the insides....there is nothing like a max flow capacity David...unless you running like 35psi or something  |

Max efficient flow would come into play waaaay before then. At 22 psi I would not even think about running a TMIC. At that boost level a FMIC would handle it much better. And b18 there is a pressure drop still. And it's about half a psi. Do your research on reviews of ppl who have actually used this TMIC.
If you want to tell me that at 14.5-18 psi on the stock turbo, the TMIC is better, then I would quicker agree with that.

Legacy_SpecB, we talkin about redman car....not ken block!
PS: do you have PSI vs RPM vs Radiation curves to support ur claim?...you sound like u do...

The saga continues
I decided to leave the entire statements with only the names edited...........
| ** wrote: | I saw one of those Perrin TMIC on a legacy wagon a few days ago. Very soild piece of hardware. The turbo bolted directly onto it, does yours do the same? I don't understand what people said "couldn't be done"? Looks good so far.
Is that Perrin Recirc valve a proper recirculation valve or a BOV? |

| But since is redman car we talking bout here and he may never cross 20psi then maybe the TMIC would be sufficient. |

| TMIC OR FMIC both has it’s advantages and disadvantages just doh forget the water/meth very useful addition to the mix. |

which is why i say u underestimate the power of a TMIC, which is why i posted the vid that i did.
This goes to show about our rising heat theory and also BIG turbo on TMIC lag, they mentioned it in teh vid. However in the following vid, BIg turbo + FMIC had RIDUCULOUS LAG:

| That's right Flex. WMI is important. And much more so when running a TMIC. Also b18b did you notice the thing in the trunk of the car???? I wonder if that car would be doing so much hp if that wasn't there? |

| Where redman? Redo I have ah question for you. What exactly you plan on doing with yuh car? In terms of boost levels etc? It makes no sense arguing which is better for you if we don't know how you plan to use it. |

| B18 btw the lag in that video have nothing to do with the FMIC. Like the guy said it is because of the massive turbo used and the gear that he was in. You would get that same lag with a TMIC. |

lag depends on what gear you are in sir....
both cars huge single scroll turbos, similar output, one with tmic, one with fmic.
they were also both in 4th gear eh.... |

Um I think I will just stay stock
Thanks
Ok
Thanks for all the info-and I appreciate flex's pride Im a man that just found the jack handle. I fully agree with his point of the comfort of ride and keepin that as the priority (if it is in fact the priority)
My issue would be what s the cost of a top mount installed vs the FMIC installed, and then look at the inc in performance per $ spent.(cant help it its my nature) The cost benefit is the first step.
Im not looking to be the fastest-I this is the last mod I would be making for a while and to be frank the ease of the TMIC switch is attractive.
With the top mount I understand that the Perrins require a little mods while you can order the AVO as a JDM spec and is a seamless mount up with a possible issue with the seal under the bonnet.
WHats the gain in HP with the 2 and approx cost?
Would I need to change the size of the turbo to get the benefits out of a FMIC??
