Question about LS1 FD's
How is the understeer in those thigns?
From my reasearch the LS1 is heavier than the 13b. So what's the deal? How's the understeering properties? Is the LS1 heavier than the 13b? |

ls1 fd's are an abomination.

Thank you for your insight.
|
Also, have the people who have done the LS1 swap admitted that it's built purposefully for drag racing?

you guessed wrong if you said the v8. but ignorance is deep around here. if you want to start shit about v8 rx7's, do it somewhere else. |

So with one Madzolet in the stable and another on the lift, I have one question-----WHY? Really, since you actually have a working 350/TII, what advantage do YOU see to doing the swap? What did YOU gain, what did YOU lose? |
The only people crying about possible understeer and making comments about weight up front are the people who have already decided they don't like the v8 conversions and are looking for excuses along with not knowing what they are talking about.

Is the LS1 heavier than the 13b? and you said "From my reasearch the LS1 is heavier than the 13b" but I dont think you understand how the LS1 is barely any heavier... under 90 pounds and this is a minimal weight gain to notice since it fits under the stock hood, especially as a percentage of a 2600 pound car and most RX7's are 2800 pounds... |

What did YOU gain, what did YOU lose? what advantage does he see?...maybe 450+hp n/a if he builds it right ( i have much faith in crash test joey) What did he gain? a badass car w/ looks to kill and hp to spare What did he lose? if he's like me then his g/f...but my car fucking owns girlfriends ;) besides what woman isnt going to want a man with a LS1/FD, providing they know that it'll beat the fuck outa most production vettes. |
Ah, there we go.
I NEED MORE POWER! MORE POWER!!! MORE TORQUE!!!! I'm not trying to start shit. Really I'm not. I just want to know why someone would want to disturb the centered balance of an RX-7 with a nose heavy car? The thing was supposed to be a front mid-ship. Not a Front engine rear wheel drive car. Even if the engine weights less, the distribution of the weight is not shifted. It's no longe an RX-7. Sure, compensate by upping the spring rates on the front. That's fine, I just hope you never hit a bump in the road. The RX-7's chassis wasn't designed to hold up to that kind of torque. Don't give me those "What about those 500hp RX-7's!!!!1oneeleven!???" Well... those 500hp RX-7's aren't making 500rwhp and 600 ft/lbs. They're making something like 300-350 ft/lbs. I don't see much benefit for having a nose heavy car that was originally intended to be a center weighed car. |
My LS1/fd only gained 20lbs with the LS1. The car now has a better weight ballance than it did with 13b.
My car runs 11.1@127 all motor no turbo no NOS and on 91 oct pump gas, not race gas like all of the fast 13b turbo motors. 25 mpg with ac and power steering still on the car. |

What did YOU gain, what did YOU lose? I originally wanted an FD first but couldn't find one in my price range at the time, and when I did I picked it up. Advantages that I see: -reliability -cheaper horsepower -more available torque -usable powerband -better gas mileage -fairly unique status -reliability :D With my FC I lost nothing - my rotary lasted 10 miles before it died. Now I have a car that I can park for two months at a time, turn the key and drive down the street without crossing my fingers, saying a prayer or pulling pins from a voodoo doll. And it's faster than every RX7 I've personally seen. (Not to say there aren't faster rotaries - just that they haven't come across my path). With the FD the only thing I expect to lose is the respect of people that I don't care about. I expect to gain everything listed above, plus a sense of accomplishment. There are about 25-30 of these swaps in some stage of completion around the country right now. I'm proud to be a part of that specialized group. |
No understeer, just some nice power on oversteer :)
I've driven them back to back, no difference. |

Also, I fail to see how you're "not trying to start shit". This topic has come up again and again, and yet you lemmings still come out of the woodwork with your 50:50 arguments and whatnot. |
The threads bashing the V8 swaps are getting downright embarrassing to the posters. They showcase the poster's lack of research and knowledge of chassis dynamics and how hard they've fallen for the various rotary myths.
I have yet to see an intelligent, rational reason against the swap. Everything that I've seen is assumptions or BS that fall by the wayside when any techinical research is done. Ben |
Bah! Just more V8 propaganda!
LOL Andrew |

Damn is it me or does every week some other rotard come in here and start the same old thing? |
Do people not understand that once you (said driver) sit your fat ass in your fd that you are throwing off your perfect 50/50 ratio?
|
No, because that entails the use of logic, a capability a good number of folks seem to lack.
