Hay guys ive been wanting to have a car that's in this club for ages.. my Mazda were just shy of it with as much as i could do to the engine without going nuts...

been reading a lot on here and was wondering if you think it would be possible to reach this magic number without charging it?

What kinda mods would be needed to reach this without charging?

Any thoughts would be greatly appreciated

Kev,

This topic has been covered many times on here, use the search key for cams, throttle bodies etc. and you will find what you are after.

Lairy cams, pocketed pistons, throttle bodies and a remap should see you past 200 if you pick the right bits but depending on how handy you are with a spanner will depend how much it costs you. Most big power N/A builds are 2k plus, which means with the price of secondhand charger kits now mainly sub 2 grand, N/A is a more expensive route to glory

I disagree it's been tried and tested on just inlet with bodies to get over 200bhp. I've never seen any gti6 engine produce that power fig with just a cam and bods

That's not just an inlet cam and bodies though !

I did not realize the charger kits were so cheap , i am pretty handy with a spanner i am a mechanical engineer to trade

however the i was asking about the N/A route as i assumed this would be cheaper than a charger kit..

By what i have been reading some of the charger kits are pretty much just bolt on ? if this is easier and cheaper i might look in to this aswell.

not looking for a HUGE power increase , maybe past the 200 mark would be fine and i am told these engines would run low boost all day long

thanks for the info tho guys

Yes charger kits bolt straight on and seem to be pretty reliable too. Quite a few people running chargers now and plenty of info on them on here too. N/A power isnt cheap. Your looking at around £1300 for 2nd hand jenveys with ECU when they come up.for sale whats not very often then you want some cams whats around another £450 then fitting ect, may as well do belt and gasket while fitting came then your going to need mapping. Probably better off buying 2nd hand charger kit and bolt it on and away you go.

All depends on how much far you go if hes only wanting 200bhp. I am running catcam 3107s and mapped ecu on standard engine at 195bhp

Or stick a set of jenveys on my engine with a new map

I've said this before recently(ish) but...... Going back 6 years or so people were allegedly fitting mild cams and having them re-mapped to almost 200bhp, what's changed??

If you've not bought a car and you're dead set on a 306 I'd be looking for a car that's already modded, you'll save yourself loads of time/money.


Or buy a clio, be faster than a 200bhp 306 out of the box....

N/A power is hard to unlock, it's not easy and it's not cheap. It's not like bolting on a charger and you're away. Air needs to get in easier, (ported inlet or bodies) that air needs to be let into the cylinders (higher lift cams) those valves need the space to open longer than they do as standard (standard valve lift is super close to piston contact already) so pocketed pistons are needed, problem with long overlap cams is you'll need more compression to make up for the fact you have to squeeze up the inlet charge in a shorter space of time (so high comp pistons with a big intruder dome are required to increase compression). The ecu needs to be told to make use of the extra airflow by increasing the fuelling (new ecu and mapping needed) if you've done all that (and you can't really do any of that on its own and expect much of a gain) you can expect some very healthy power and an exciting drive. However as that little lot can easily set you back by up to 3-4k it seems too much for too little.

Seems to be coming back seen a few people hitting, 200bhp+ on just bodies..

Seems all you need in reality is a generous dyno lol

Rich_W made 204bhp on just a set of PT81 cams, with standard inlet before he went down the charger development route.

If I'd agreed with you, we'd both be wrong.
