mines high flow throttle system
 

hey guys came across this, seems that it has been out for a long time but haven't seen anyone try them out, they seem interesting from what i have seen and read, the gains are really good when installed on other cars, don't really know how the 370 will respond to it, just wanted to know for these parts does it make a difference if the car is a LHD or RHD ?

all I know is mines is on crack with those kind of prices for parts. hope that is in yen. lol!!

Holy *&^% MSRP $1,700 :shock:
I was just wondering about the throttle body the other day, can't a machine shop do this for much less?

yup a good machine shop will not have a problem with that
it cost me 500$ to do both of mine.

What did the gains look like? Did they do just a traditional port and polish?

I'm guessing about 10 whp at best... LH or RH drive shouldn't matter.

The ECU is more intriguing to me -- they claim retuned VVEL.

Did you gain anything from boring your throttle bodies ?? I am thinking of sending mine to Max Bore ...

this... While I love your willingness to buy all these baller parts.. there are just not enough gains to justify that price tag.. IMO

So you guys think its a firm no?

post up the results from your cams first because I hope you prove all of us wrong! (I would get them) and give this a shot after!

That's the plane my friend :tup: cams on order pending Jun's reply

the quick test showed a peak gain of around 7-9whp last year
since I had a problem with a cracked flywheel which caused the knock sensor unhappy (vibrations) we decided to not fully tune with the bored TB to much

im positive the gain are there and valid..
but again the bored out TB is not the one from mines company but a company here in Toronto who did the job on my OEM TB

in NA form in general it cost about 100$/1whp once the car is fully completed by basic bolt-on..
so if I gained a good 7-9whp for 500 $ & 100$ gas money it showed to be the norm..

anyway
all that big talk right now wil re-confirmed in mid-april
if the test doesnt show anything good ,, well atleast I would have tried.

7-9 rwhp for $500 is worth it IMO. Looking forward to dyno results.

I did the test again and the gain are there !
but is it worth to spend all of that $$ for little gain ?
for a street car , not really but for the track if you have the budget then do it.

and at the same time I confirmed for my own personnal knowledge
the HR vs VHR intake manifold

Awesome results. Any retuning? Or was this just strictly dyno pull comparisons?

I tried to adjust the AFR but not much could be done..
maybe 2-3 whp could be gained but im gonna change back to the HR intake manifold.

Impressive midrange gains with the HR mani.

Do you have dynos of oem tb + vhr mani VS 62.5mm + HR mani?

I do not have an overlap of the 2 options you asked
but
if you take Run File 18 = 323 whp = VHR intake manifold + Oem TB
and Run File 9 & 10 = 327/328 whp = HR intake manifold + 62.5mm TB


the HR intake manifold is the winner unless you only want the advantage of the VHR at 7000+rpm
adding a bored TB you pretty much only gain anything between 5-9whp


keep an eye on my future project during summer time ! :) (2x 70mm TB)
