exhintake questions

[92_escort_gt]

i have dyno proven results in a N/A miata...., seemed to make a big difference im my EGT.

[dave0r]

Rob posted his results on another forums

didnt appear to work for him, thats not to say it hasnt worked for others
or maybe the others are not sharing 1 vital bit of info to make it work

ive still got no shed atm and this N/A motor with the ExhaustINT isnt going ahead just yet ..more delays

i'll be on the dyno and doing compression tests with BP22 cams, BP05/06 combo's to see what happens , then i'll EhaustINT it with what i have, Gen1 gen2 cams..etc


im guessing the timings out for Robs astina and its just blown'n out the cyl
then again
Carl (al4spn) had the same issues when he switch to a N/A head & BP26 cams, made no power and wouldnt boost upto 18psi anymore..swapped back to BP26 head, problem solved


just luck i guess?

yeah it all sounds good on paper , more lift and duration when dialled in should net results , i just havent seen any yet that prove to myself its worth doing

my car seems to have no issues, its beyond my comprehension.
just for clairification rob used the turbo exhintanke version, the NA version is dyno prooven with graphs to show gains.

[dave0r]

i agree,, it appears to work well with N/A builds

im guessing in a BP26 ExhaustINT setup the overlap may be too much all between the cams

id thought that adjustable cam gears would help over come this, but Rob has these...

oh well

[FE3-323]

that thought is incorrect. the whole point of the turbo version is that you keep the GTX cam overlap.

While the NA version increases NA duration from 19° to 21°

I think im going out to take a damn picture of MY CAR/cam gears @ TDC & post it in the proper thread about it.

[Skuce]

Probably a good idea man. Seems a lot of pl are getting misinformation. Cause all the numbers work on paper and apparently a few cars.

BUMP!!! updated with pics.

[TREVO123]

Could some one post a picture of where i should mark the New cam gear for the cam? to base tune it, as for im using the stock cam gear for now, and wont be uprading to the Adj cam gears for a bit, but want a little bit more power!

90-94 1.8l dohc bp05

[Wombat]

Or would his be a 1.8L SOHC B8 since the title on the post said 91 dx? Either way it's a 1.8L for sure.

[FE3-323]

dx=B8 sohc

Ok we talk about 8 to 10 HP - but what about torque?

rigth'o

this ExhInt mod this isnt working for me yet!! 138whp..it doesnt really feel it after driving it for 2 weeks

im using a BP05 exhaust cam from the BP22 engine on the inlet
yet the car makes NO power like it used too (this thing used to have mega power!

my question is

are you US people using a BP06 cam from a USDM
or a BP06 cam from a JDM

the last thing i want to do is swap out the BP05 cam and put my BP06 JDM cam in to find its no better !

it looks good on paper and you US people have dyno results to show it works..but i never really saw the USDM or JDM bits ..

any help cheers
as tomorrow im taking the cam out ...yet again...and putting in the JDM BP06 exhINT cam.

if it doesnt work then im putting the BP22 inlet cam in...
