am guessing the ecu which comes with it might advance the fuel mixture due to more air coming in via the induction kit resulting in the 10% increase but you wont know until you have your car dyno'ed before installation and after installation. I am currenlty running 99 ron and to me it feels like 225 or more bhp to be honest. a BMW/VAG Tuning company near where i live does dyno runs so might stick it on the dyno for the hell of it and see what figures i get from my stock engine with the Apexi and V power so watch this space

Nice love it :-)

SRT offers an induction kit with race ECU upgrade but dont have one at the mo..decided to stick with high flow panel filters instead as i prefered the queitness but the Apexi i have changes the engine note once i hit 3000rpm. SRT cliams a 20 - 22hp gain with the ecu upgrade aswell http://swiftracing.c.../item.aspx?id=2 other guys in US are using the Joe Z tube which has been claimed to officially give 7 bhp more to the rear wheels. http://l-tunedparts....roduct/?id=2853 was tempted to get this tube to accompany my Apexi filter but thought will i really notice 7bhp gain on the road?? so SRT is worth looking if you decide on induction kit.

mmm..lottery that reminds me its Wednesday will put my £1 in and see if i win LFA money :)

10ner on its way Mikey :)

spot the similarities and will pay you a 10tener :) ??

you welcome mate.

depends how one drives but i range between 16mpg on a bad day in town(flooring it) and 20mpg on a good day in town driving...30 to 33 mpg on a long motoway cruise using cruise control. didnt buy for mpg either

Mass Air Flow sensor mate. works out how much fuel gets chuck into your engine or how the car should respond depending on the amount of Air being drawn in. steps on how to do this below mate.. http://my.is/forums/f67/is300-cleaning-mass-air-flow-sensor-maf-340945/

hello mate just pull out your negative battery terminal/wire for about 30mins, replug it in and job done. noticed most mentioned about auto box fluid needing change but no one has mentioned MAF sensor cleaning as this could cause hesitation or slugishness when dirty and could improve MPG aswell when cleaned.

one thing I do is hold my hand up when am wrong. and in this case I was wrong its not over yet but will that stop me from rolling on summers and snow mode on the M1 tommorow?? you guessed right...

I know that feeling to loose your 20's mate

again common sense should tell you they needed it for thier 3.8 litre to make that power just as much as an IS300 should need it(turbo) to make that power. very dissapointed in you matt :ooh-ducky:

but common sense should tell you in order for them to make a V10 500BHP figure in the GTR, they need go modify(Turbo) to do this. this results in a 3.8 litre sucking in rougly the same air into its cylinders as that of a 10 cylinder 5 litre to make it happen. you dissapoint me matt thought highly of you. honestly i did

you being a chicken and silly now matt.Tell that to Nissan GTR drivers. let me know how deep you have dugged that hole for your self. like i said you come across very intelligent :D

haha :D ..thought we have always been talking about apples and oranges? why steer away from it all of a sudden and start renaming to modified and standard matt?? thats so not fare!! ok let me ask you a queation. in order for a 3litre to be brought up to the level and when i say level i mean horsepower. in order for that 3 litre to come to the level of a 5litre V10 500bhp car what needs to be done to the 3litre engine? once you have answered the first question successfully can they now be classified as apples with regards to thier BHP?? if no tell me why?

matt lets go back to nursery school. there are 2 baskets 1 lablled apples and 1 lablled oranges. now teacher Noddy hands you an IS300 toy car with turbo 500bhp printed on it and also hands you another toy car with BMW M5 NA 500bhp printed on it.. and says hello matt lets play a game called toy in a basket. and says can you place all the turbo cars in the the basket labled oranges and all the NA cars to apples basket. which you then did succesfully. she says good boy and then says hello matt, can you group all cars with 500bhp printed on them into the baskets. now am asking you matt will both toys end up in seperate baskets?? if yes, explain why?.

haha i smell chicken!! common sense should tell you in order for a fare race between the two, thing have to be somewhat equal between the cars for this to happen. like i said matt you come across an intelligent boy and i applaud you!!

Love it I know very well how power and torque ratios work. So, what you are saying is.... If I turbo charge my IS to 500bhp @ 6000rpm If the F3000 is 500bhp @ 10000rmp Add weigth to the F3000, or remove weight from the IS300 to make them the same. ..... they will both do 0-150 in the exact same time? Dream on. Okay, now lets see all the pointless numbers and equations you'll post that will..... cancel out aerodynamics cancel out different torque curves cancel out different bhp curves cancel out the gear ratios In different cars, 500bhp in one may well be the same as 500bhp in the other, but it doesn't make the whole playing field the same. One may produce 500BHP for a 500rpm range, the other for 50rpm. I admire your enthusiasm, even if it is misplaced at times. am admiring yours too but there is one flaw. if F3000's engine produces 500bhp across 500rpm range and IS300 Turbo engine produces 500bhp across 50rpm then torque curve hasnt been cancled out then has it TigerFish?? if both engines make the same 500bhp and you cancel out aerodynamics, bhp curves, gear ratios and most important torque curve and i say most important because torque gives birth to horsepower(most people think they dont relate to each other). then 500bhp for both engines will only run across the rpm 500bhp is made and then drop off once they go pat that rpm why do i say this?? i say this because for any car on this planet to make 500bhp over 500rpm range it would need a flat Torque Curve. have a flat torque curve and you will have 500bhp across 500rpm . cancle out a flat torque curve and you have cancled out F3000's engine from making 500bhp across 500rpm. which will result in it making it at only 10,000 rpm and then fall off. so if i cancle out torque curve as you suggested in your list then guess what? none of these engines will make 500bhp across 500rpm. this ability will also boil doin to if the F3000 engine has 500 extra more revs on the rev limiter to play with once 10,000rpm is reached but if fuel cut off is set at 10,050rpm then guess what TigerFish this 500bhp across 500rpm will not be possible either. I await your response on this

Don't get me involved, I only drive them! :lol:

yes Tiger Fish this is what I am trying to let matt know. power is power regarless of aspiration or weight of a car. once you balance the weights of both cars, either by increasing the weight of a 650KG to 1500KG by adding 850kg to it or decreasing the weight of I300 from 1500KG to 650KG they will both be equal and one wont pull any faster than the other. please explain how Torque chucks both arguments out of the window?? infact torque rather gets chucked out of the window if both cars make 500bhp at the crank. why? this has always been the formula of calculating BHP. Torque(lb-ft) x time (rpm) /5252. that is (lb-ft * rpm /5252) so if the IS300 makes 500bhp at a redline 6000rpm, it will need to make a whopping 438lbft(593NM) at 6000rpm to yield 500bhp.below is the formula. 438lb-ft * 6000rpm / 5252 = 500bhp if the formula 3000 engine makes 500bhp at a redline 10,000rpm , it will need a very small 263(356NM) at 10,000rpm to yeild 500bhp. below is the formula. 263lb-ft * 10,000rpm /5252 = 500bhp so can you now see why torque gets thrown out of the window if both engines makes the same power at different rpms? the formula 3000 engine makes a small torque of only 263lb-ft(356NM) but yet still is was chucking out 500bhp at 10,000rpm. IS300 Turbo engine had a more 438lbft(593NM) at 6000rpm but yet still made 500bhp. so like i mentioned in my first post, if the IS300 is reduced to 650kg to match the formula 3000' weight, it will pull as fast once it kisses 6000rpm or vice versa, if the formula 3000 car is increased by 850kg (650+850) to 1500kg which the the current weight of my IS300, it will wont pull any faster even tho it revs to 10,000rpm. like i said power is power regarless of aspiration.

man up and come over matt you can bring budy ray along if you wish..

which is faster? guess what matt they both the same. why do i say this? lets say the formula 3000 car weighs 650KG strip the IS300 from 1500KG to the same weight of 650KG and it will pull as fast as the formula 3000's car either on the road or on the dyno. or if you wish add another 850KG to the weight of the formula 3000 car to total 1500KG and it wont pull any faster than the IS300 with 500bhp now does that make sense?

matt and ray I have started a new thread called 'bhp' at the Lexus lounge lets have this discussion there if you wish..
