Ahh sorry I asked bolt ons prior to uprev?

Neat!! In terms of peak power, on top of the above what bhp would be expected from an uprev and do you find its worth increasing the standard rev limit or not really?

Good lad

Ahh got yah, sure they'll hook you up

On a healthy ukdm DE, prior to uprev what gains can be expected from bolt on breather mods? Ie exhaust, aftermarket panel filter, HFC and plenum spacer..... And of the above hardware, which do you rate in terms of bang for buck? David

Price in subject....

Ello n welkom

Yes please for Combo, you have PM David

Sorry to see this, really terrible. I read it think ffs man

Why would one buy these over say yellow stuff?

Seen Mark's Zed a couple times now, love it for the hard work and truly one off trick mods but for the fact that it's always SUPER CLEAN too!! No dirty to be seen anywhere.

side note - more issues are probably caused from installing oil based WAI inconjuction with the MAF. Dirty MAF = lean mixture and mods are blamed above all else.

Appreciate it Mark

ickle J reg Sunny is paying dividends in these conditions, 350z you stay in bed and rest up

This time of year everyone had their heaters on, so you arrive at work inside of car is warm outside little above zero. You jump out lock the car and all this warm air inside the car rises and comes into contact with the cold glass, the rest elementary. Jap car of the same era don't tend to breathe as well as they should resulting in condensation. Just before I pull up and I'm warm, if I remember il switch the direct to the cabin and heaters to cold for the moment to try and help matters.

The general thinking from that link to the same debate over on my350z forum way back in 2005 is that and I quote: there is no way the ecu can equalize or negate the power gains added by parts. if you add an intake and exhaust to the car, the ecu will not re-adjust itself back to stock HP etc.... That's was a trader from a tuning company in the days. Also Nissan, supposed when they use to get involved with such matters on a technical level concluded the same.

In the nicest possible way, so why was the thread started.... All I've heard so far is heresays without any backup. Saying something over and over doesn't make it any more true. I'm new the whole 350z/370z and when I hear something that doesn't make sense, il ask the question. The ecu doesn't dial out any gains seen once it's had chance to learn the extra air going in and out of the cylinders. Ecu see's more air, resulting in a lean burn so adds extra fuel to maintain ideal normal driving afr. Using super unleaded fuel which arguably is better than when the car was launched for the UK market back in 2003, all helps with high rpm ignition timing and boom gains in power. If with bolt ons the ecu manages to control the afr in a way it see's fit, most gains from the remap for n/a vehicles generally come from advancing the ignition timing. That's my 2p anyways. What's the standard base ignition timing for the early DE's? David

I'm sorry but I'm laughing inside...... delete this useless post or not but there's been such strong views towards this topic however when it comes down to it silence fills the room. Please someone put this to bed............

Both, you'd hope that a reputable outfit would have fairly accurate figures. However dyno hoping isn't great as there's too many variables. Any figures from a solo dyno visit is to be treated as a guide and if you as a customer feel that the figure is close to accurate (as Steve does) then you kinda have to take his word for it. Ie local knowledge of other cars whereby collectively results seems fair. Not always possible but it's advised to stick to one place to try and gauge gains throughout the modding venture. That's why rolling road meets can be useful, as both modded and standard cars do their runs. If a well maintained standard car puts out standard power, then the results from that day foul play aside are about the best your going to get in terms off accurate brake, hub or single drum inertia dynos.

Comparing figures from two different rolling roads isn't a straight comparison, too many variables.

Well done pal, had one of these in my ol Almera GTi n loved it

just dont believe a standard DE on the same dyno would make anywhere near whats shown on the OP...... furthermore ive never seen/read it happen either and Steve's has so...... yet to see any evidence of bolt on gains being dialled back to stock bhp/lb-ft once the ecu has had chance to settle down ie the same way that OP has had time too between the point of bolt ons and the dyno run.

you're hypothesizing and creating random bhp figures and expect a straight answer to a random through away figure...... i believe next month at the same dyno Steve's car will again make the same figure all things being equal, ie dyno setup, air temp, wheel alignment, no brake drag, wheels, tyres and tyre temperatures all the same of which have an effect on whp. YES Steve's car would make the same fugires in a months time. answer based on actual figures, not guess work. David

Here should be OK long as Steve don't mind....... Point 1 - No, tuning isn't mods by numbers every engine response differently to bolt ons. No gains, not event standard cars maintain its power forever so why would one with bolt ons..... an uprev doesn't mean you'll maintain gains forever either as natural engine wear and tear will always occur regardless. Point 2 - I've yet to see any evidence to confirm your thinking. My question is simple, on a reputable rolling road has any 350z DE with bolt ons ever produced more than 276bhp? *mods fitted weeks before dyno visit. David
