wow the parts that jumped out to me were these:
just those numbers alone make the CR-Z even more interesting than b4... especially the raised rev limiter... i wasn't sure how high the stock motor can go w/o damaging something but it seems like it can handle the added power and higher revs... those numbers also put it close to the USDM stock civic Si numbers... lets hope that the hurt fuel economy of 25c/29h was just in Sport mode... if econ can retain 35h+ then that's a real winner... my question is, why didn't Honda release the CR-Z with these specs in the first place?? |

Also read $8000 in parts. All that to make it match a Civic Si's performance. So is this worth a stock civic si which has all the safety and comfort features and less $8000? |

some of the performance comes from the weight loss and some comes from parts. but we don't know the extent of the engine work. so if they only had bolt on parts such as an intake and exhaust along with the 200lb weight loss (stock engine internals), then most of the performace would be from the retune. an ecu flash is essentially "free"... so honda could've made a better ecu map and the car would have more power and the car wouldn't have been much more expensive than it is now. not saying a retune will match a civic si but it will make the cr-z faster without a lot more money right ? (because i think that most of the 8kusd actually goes towards the wheels, coilovers, front sway bar, exhaust, etc) <-- nothing that'll affect the engine too much and im gonna assume honda didn't do this in the first place because they didn't want the already low mpg to go any lower and they wanted to keep the emissions down. |

well some say my '06 Si was a freak b/c i never dyno'd lower than 190whp/139wtq even while completely stock... TB spacer and some heat gaskets had me at 195whp/146wtq... another great thing about it is i averaged about 26-28mpg combined city/hwy and that's while vtec-ing EVERY time i drove it... getting over 32hwy mpg wasn't hard at all either for me... i only say that b/c the numbers they stated sound really conservative to me... 25c/29h even if it gets those numbers in "Sport" mode that's pretty decent... i'm sure "Econ" mode gets well over 30mpg... also read below for the rest of my response Quote:
so my assumption is, this power came from ONLY tuning, lower vtec, better A/F, not to mention raising that pitiful rev limter... which, btw, would be one of the major things for me to NOT get this car... if i can't rev it at least to 7,500rpm w/o major work i'd rather get something else... when the current Si/CTR came out, Spoon got a hold of one and modded the engine to rev to 11,000... they did this by swapping the K20A crank with the F20C (S2000), they also swapped the pistons with the H22 (Prelude)... upgraded valve springs/retainers... it made 250hp @ 9,500 which was up from the 225hp @ 8,600... the thing about all that is they TOLD us what they did essentially... they didn't leave us thinking it was all stock parts... so knowing that and the kind of company they are, i'm going to assume that it is like i said above... a tune + exhaust + "Sport" mode and nothing else (for engine performance)... my cars are NOT race cars so weight reduction for the sake of gaining .5 sec at the track isn't something i do... hell my Si race weight was 3050lbs and i still managed to get to 14.9 (1/4 mile) 100% stock while others with I/H/E, removed seats/spare tire/etc were only getting to 14.5-15.1... point for me is, if the engine performance is there, i will make the car perform above standards...

in fact, if i can get my CR-Z to do something similar to that, i will have no intention of ever selling it... |

oh sweet now we know what spoon's new wheels are. thanks~
also, if its just exhaust + tune like you said, then i really feel that making the cr-z do what spoon made it do (engine wise) wouldn't be too expensive. because the spoon cr-z has coilovers, brake calipers, wheels which would add up to a bit more than 4k. so thats already 4k off the 8k for the complete spoon package. minus whatever else they did that doesn't add those horsepower, then the leftover price goes towards the exhaust + tune which is what added the power. oh and i hope spoon gets us a dyno graph of this new tune + exhaust. i really wanna see the new power curve vs. the stock one. |
