Ive finally got my car running really well and im ready to get it mapped at MSD. Only thing is i had a de-cat pipe made up simpson racing exhausts and they basically told me my current exhaust setup is shit. Im running a trust electrical four branch and full magnex system. They have told me if i get one of there equal length manifolds and one of there systems with 2.5 inch bore (mines 2inch at the mo) it will improve my car no end. Apperntly the current exhaust system will be strangling it at high revs.

does this sound right as my current setup wasnt cheap and a full system with manifold off them is 825 so alot of money to just waste for no real gain.

So im a but stuck now if im gonna see some good gains then i will hold off on mapping till i can offord this system. but if the gain is really small it aint worth the wait or the amount its gonna cost.

Dunno what to do there systems are well bling but maybe to bling for my state of tune i dunno. any advice appreciated

 

My Mongoose (for a 4x4 sapph cossie) gained my approx 10bhp and singnificantly improved throttle response.

yea i can see that you will get big gains on high powered turbo cars. but what about my moderatly tuned na 2.0 zetec

 

On naturally aspirated cars it's easier to loose someting than gain. But you may gain quite a lot with right exhaust, cams, headwork, intake and so on.

 

Tell them that you buy it on a try before you buy basis...if it doesn't make a difference then they can have it back and you don't pay a penny....

 

and they will say like fukk!!!

 

yea ill just say " can you spend the whole day custom fabricating a bling exhaust for me then if i dont like it can you take it off and i wont pay you a penny"

 

my experance is that on a na car it really wont make much difference unless you do the lot, ie exhaused, induction, cams, headwork ect. if you already have a performance exhaused on the car and a 4 branch manifold then i really wouldnt waste the money some things these companys tell you really do need to be taken with a pinch of salt in my experiance might gain you 1-3 bhp over your current system! just take the rear seats out and you will gain the same performance improvement

 

Yeah sounds like they are trying to stiff you.

Now, if someone who DIDN'T make a living selling custom exhausts told you, then that'd be different

 

i dont think he was trying to stitch me up, they wernt making out like id make massive gains . There jsut saying with there system i would gain about 5lb/ft a few bhp and the power would be moved up the rev range and the car would be alot better in the higher revs which is what i want. just dunno if its worth the money. Im thinking maybe just get there system less the manifold as the manifold is the expensive bit.

they do seem to know there stuff and some of the cars i saw there were fucking awsome, had a lotus elise with a 210hp vtec lump init, a stripped out rwd nova , rwd 306 with xe lump on trottle bodies

 

Well you never said that they had to custom make it!!

 

i bet you, you will not notice any gains from it!

ive got a focus ST170 4-2-1, decat, and powerflow system.

does the job mate

 

DONT BOTHER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!


spend it on something else for the car thats worth while

 

oh yeah, and for £800, get some throttle bodies!

 

yea im thinking now that i could get nos for the kinda money they want and that would obviouslly give me more power

 

t/bs!!!!

 

yea i have been considering throttle bodies and would like them as it should give me near on 200hp with them and all the other mods i have, which would make for one rapid car. but ive always said no to them cause i dont want my fuel bills going sky high as i use the car everyday and do loads of miles.

 

so do i, but im gonna having some nailed on soon!!!

 

plus ill have to ditch the current management and wire up whatever they come with . Omex or DTA or watever. is this hard. seems alot of work really but it would sound the nutts.

 

im gonna be using SECS S8 management, hopefully the 1st in world to use it N/A!!

unless me mate beats me to it the fukka

 

what throttle bodies are you using with that then, and how much is the secs gonna cost ya

 

i got some GSXR t/b's, just need a few more bits made to get them to fit, and can say on S8 yet as i dont know the total price yet

 

Are yo really gonna notice a few lbs/ft for a cost of £800+?? Don't think so mate. As above, buy something else if you've got it to spend!

 

that's the beauty of turbo cars over n/a in my eyes. i used to spend a fortune on mk1 & 2 escort bits and bobs to make not a whole lot of difference in power. you can piss about with air filters, different carbs, manifolds all that malarkey. then i got a cossie which starts off with over 200 bhp and to get another 100 costs you a 3 bar map sensor, a set of greens, an actuator and a chip - also about 800 quids worth.

i've learnt over the years that it's all too easy to spend too much and hardly notice a difference. fair enough if your racing and have to fit within regulations, but for the road it's best to start with the biggest most powerful engine you can fit in the car.

like you say, you can get nos for that money for a far bigger gain and you'll definitely feel that you've got something for your money. you'd be able to sell or transfer it as well, unlike the custom exhaust.

 

Tuning small engined n/a cars is a poinltess waste of cash IMO

 

 

yea if your going for big power then yea it is pointless. I was gonna go zetec turbo but i wanted a relible car with good fuel consumption and cheap insurance but still packs a punch. My fiesta fullfills all of my requirments, its grp 8 insurance as it rated as mondeo with Adrian Flux, i get around 200 miles to the tank if i dont rag it, the 2.0 zetec is a relible engine in na form and i embaress alot of higher powered cars . so im happy with what i got for a daily runner.

once ive got my 5th years no calims through i will be looking in to something stupidly powerful prefably rwd and turbo'd for my weekend/fun car
