1st you have to decide what you want the car to do ?
1 do you want a really fast road and track car . = t51spl
2 do you want a drag car ? = 1st choice on rb26 t51 or t88 if you want plenty of lag.
put it this way if you had 800whp say thats produced around
[email protected] say 2.5bar boost and you went against a 600whp produced at
[email protected] boost who do you think would win?
its not always big bhp what makes the car fast
its how well it uses that power and how long it takes to reach there
personally i would go for spl for the spool and yes you would get 800whp with ease
top end would be a fraction difference between t88 and 51 on rb26
id say on drag strip and local driving t51 would win even if it had 600whp
a really laggy turbo is boring to drive
im suprised my t51 isnt laggy at all i was personally expecting it to come on boost around 4500rpm but comes on with my setup at 3750rpm and and full boost is reached at 5000rpm car is limited to a safe 8250rpm mark due to standard balanced cranck
but trust me i have never used the full power of it anywhere
you just cant
it breaks my heart when i see the needle moving
that is the fuel needle btw lol
