Currently i have BMR billet LCA with relocation brackets, BMR adj UCA, FRPP springs, intake, exhaust and a 150 shot. I dyno in at 435whp and 565wtq. I want to do gears as my next mod but unsure to go with the either 3.90's or 4.10's? I dont want to lose alot of top end because i do like to do roll racing usually around 40mph. But im not sure if the 3.90's will make much of a diff either. What do you guys think

 

4.10's wont make you loose top end..just shift into 5th and keep on pulling man. some people here will tell you 3.73's but if you have a good tire there sint much wrong with 4.10's

 

The only thing tho is that im not trying to spray nitrous in 5th gear. Wouldnt want to have to go to 5th just to do a roll race up to around 120-130

 

if I recall correct I think it is still pulling retardedly hard in 4th around that mph myaself and mustangbatman ran hard one day and slammed it into 5th I think it was just around that mph aswell, we shut it down pretty soon after that though, plenty fast for street racing man.....

I have 4.10 and im only running my 75 shot but with my other mods its got me just shy of 400 rwhp as a guesstimate. And trust me man it pulls like crazy in 4th and your going dam fast . you want to be street racing any faster then that then ur a brave dude....

 

I think im just going to go ahead and go with the 4.10's. No one seems to have anything bad to say about them and not enough reviews for the 3.90's.

 

ya man I would go for it, you see alot of the guys who are blown now switching out to 4.10 cause they actually rode in another guys car who was f/i with 4.10 and they loved it

 

Did you upgrade your fuel system at all?

 

I just hope i can catch traction lol She already brakes the tires loose just gunning it in 2nd gear with the nitrous

 

4.10s are good up to 130 after that 5th gear will own you

 

5th still pulls pretty fawking hard if u ask me when your rpms are up high its no slouch thats forsure.
