90 RS VS 89 Mustang

Ok me and my buddy love our cars but he thinks my car will smoke him and i think he would win but i didnt tell him that.

His car flowmaster muffler original pipes. 5.0L

My car 305 everyhting is out of my car though. all a/c and all emisions.
i have the flowmasters from the y back. no cat.
got shift kit
got rid of air cleaner and put an elderbrock on it.

so what do you guys think from a dead stop and a roll?

thanks
kevin

Agreed.

I also think he'll win by a significant margin. He should be running low 15's at worst... mid 14's if he's got decent gearing and can drive.

Dont race him especially if hes got a 5 speed. L98s even have trouble with those.

Re: 90 RS VS 89 Mustang

An auto gt is still going to click off high 14's maybe better depending on the gearing. Id guess your running a very low 16. Do what you want, just dont put any cash on it.

Re: 90 RS VS 89 Mustang

a 305tpi 5 speed can take a mustang 5.0 with 5 speed. never would of thought that. just b/c they have more power and are lighter.

if it was a hatch or a vert then its an even match, but a 5 speed notch is capable of mid 14s, but he should take you unless he screws something up

He did have some extra weight... if you had no passenger.

Re: 90 RS VS 89 Mustang

Ya we both had full cars. 4 people in each car! His mustang is nice only if he would take care of it. But it was fun b/c he just kept falling behind.

A 305TPI 5speed depending on options and year could have had more power and be not much heavier than a mustang gt 5 speed from the same year. Think about a 1LE formula.
