well heres the story about this...

I put my race motor into my daily driver to play around with over the off season..

the car was originally put together with everything out of my race car minus the fuel system. got it running on pump gas and made 508hp on about 12 psi with the T72.

drove it around for a few days and switched to to e85. got it up to 608hp on 18psi. head to the track last night and the shaft breaks on the turbo. didnt even get a pass in.

I had a precision 62/62 laying around here so i threw it on to be able to drive... here are the results

blue line 62/62 on 18.5 psi red T72 on 18 psi


setup consists of

2.0 ltr gsr motor
84.5mm cp pistons
eagle rods
ported gsr head
skunk2 pro1 cams
victorx intake manifold
topmount manifold
speaco intercooler
hondata s300 with boost control
1600cc injectors
single modded 255 fuel pump wired direct off relay
e85

 

Great results! Would it be possible to post an SAE graph or pm me an SAE graph?

 

awesome. I would deff. sacrifice some top end for a power curve like that (for a DD). What is your peak tq? do you have a graph for that?

 

it made 610hp holding 18.5 all the way to redline sae.. this graph i have the boost ramping down as the rpm goes up cause its running out of fuel...

this pass was about 16 psi at red line and sae on this one is about 6-7hp less

 

my rpm pickup is wacky..only reads clean on k-series cars... i dont use it on mine

 

how does it feel compared to the t72?

 

well itrs pouring rain oput so i havent even pulled the car off the dyno yet

 

man great comparison.

 

Great stuff, 62 billet doing work. I love my 6265, these 62's are great Precision units.

I would definately take the 62 over that t72, the little peak power lost in that route is more than made up with the overall much better power under the curve.

Nice work, good post!

 

did you log boost?

 

6262 is a broad powerband turbo for our cars no doubt! good comparo!

 

good stuff.

 

Good!! .. Cuz I know you would of ripped it up and down the damn street in front of the shop like yours crazy... LOL

Nice numbers and comparison nonetheless.....

 

.82?

 

of course.. i datalog every pull


the 62 is def a bad *** street turbo... the T72 serves its purpose at the track. ive made 895hp on strait boost with the 72mm. most ive made previously on a billet 62 was 710hp

 

awesome graph. cant wait to get my 6262 setup installed on my s2k.

is the 6262 a bb unit or jb? and i am assuming .82 exh housing. also, are you using any restrictor for it?

 

exactly what I want to know, I'm leaning towards BB since the t72 was bb.

 

x2

 

6262 is jb .. but u have the option to get in in bb for like $500+ from wat i can rember.... best jb turbo i ever bought.. hers a quick flick i though would be nice.. my 6262 billit powerd rhd eg hatch

 

nice comparison... I think i am going to pick the 6262 over the s362!

 

yes...which is why i was asking him if his is jb or bb.

mine is ceramic bb.

 

good comparison!

 

608 WHP on a single walbro on E-85.....


God damn dogg.... i dont believe...


do you have a graph of the A/F?

 

im pretty sure his is jb also cuz he didnt put BB6262 like he put bbt72

 

good power

I'm surprised you did not run out of fuel
