I would like your input on how much HP you think would be possible on my setup with a 60-1 .96 A/R undivided turbo...

'87 Turbo II, stock rebuilt engine, no porting
E6K, straight pipe/no cats, Apexi Dual N1s

I was hoping for a 400 flywheel HP target. How much boost would be required in your opinions to reach that goal?

 

I am not either one, but you will need to provide more details.

Fuel delivery, Injectors, Fuel Rails? Intercooler, Ignition system, manifold, Intake, Downpipe size, Exhaust size,
etc..

There are just TOO Many variables to give you a correct or realistic answer.

 

I'm not really looking for a perfect HP answer, just curious as to if a 60-1 on a pretty much stock 13BT would be capable of 400 flywheel hp, or if that number would be too lofty of a goal.

Fuel Delivery - Stock injector layout, controlled by Haltech E6K
Fuel Injectors - 550cc Primaries & 1200 Secondaries
Fuel Rails - Stock
Intercooler - Custom FMIC
Exhaust Manifold - HKS Cast Iron Undivided
Ignition System - Stock
Downpipe Size - 3" (or bigger depending on 60-1)
Exhaust overall diameter - 2.5" to max N1 size

My question came after reading some of the 60-1 debate posted earlier, I just wanted to get some input on this. In all honesty I'd be happy with 350 hp and work up from there, just haven't been able to find too much info on the 60-1.

 

Just did a TII with the same size turbo! Best run(cool pass) on the dyno at 15 psi was 362 RWHP with 350 RWHP being the norm at 11.3:1 A/F ratio.
Stock motor at 94K miles with low compression on the rear rotor. Turbo was a 60-1/.96/P-trim on a HKS cast manifold with the std HKS wastegate. Custom front mount I/C.
ECU was Haltech!

This should be no problem at 15psi with this turbo.

Excellent, thank you both for your quick replies.

 

What kind of timing should be run on a setup like his? Maximum advance, I mean? I laid down 269.5 RWHP on my old stock ported motor last week. My setup includes:

Haltech
60-1 full turbo
Greddy FMIC
550/1600's
Walbro Fuel pump
Trust 40mm wastegate
3" exhaust
Kinda crappy custom exhaust manifold

This run was made at about 10.5 psi.

Does that sound reasonable, or should it be slightly higher?
