BW EFR7670 Manual Result

 

Manual now, and manual is way laggier than the auto ever was (and it shows in the dyno)

12psi and 18psi runs both on E85. 98 is only about ~10kw behind as the timing is pretty conservative on both runs and it's not knock limited on 98.

Why so low boost? Misfire central at anything above 18, and the boost control isn't exactly steady as I have a 9psi spring in the gate. If I could spare about $2k it would get R35 GTR coils and 7psi more spring to see what it could do, but in all honesty being RWD on street tyres it is lively enough as it is, and best to show some mercy to the gearbox.

Now someone just needs to buy it

-El Cheapo Budget Build-

Rb25det S1 with supposed '190,000kms' bought off ebay for $650

ebay 555cc injectors $300

ebay 'maxpeedingrods' 53mm bolt on turbo $200

second hand GTR intercooler $100

ebay ffp $300

second hand splitfire coilpacks $200

ebay boost controller $35

Nistune rb20 ecu $250

Engine had a huge exhaust manifold leak because I reused my rb20 exhaust manifold gasket like a cheap ass. Also the boost controller would spike to 17 psi and then drop to 14 psi and would fluctuate up and down. Tuner couldn't turn the boost up anymore. Gonna get a good boost controller and shoot for for 220kw. 

212kw on 14 psi caltex 98

Retuned today-had a few hiccups early on but ironed them out and Decs got down to business.

Only thing that has changed from above is the pon cams have been changed for Camtech 268-9mm intake and 272-9mm exhaust.

22psi and dropping off to 18psi at top end.

326.9 kw ~ 546.8 nm

Happy with the results, think I will leave it alone for a while  

 

 

Changes from above:

Link ecu G4+ Storm. Full wire in

PRP crank trigger setup

RB26 ITB setup

External gate plumbed back into the exhaust.

315.7kw. 491.2nm. 20psi

 

Ready to go flex fuel but only had time to do the tune on 98 for an event last weekend. Car feels amazing to drive on the street and track, few small teething issues to iron out but nothing too hard.

Believe new technology is where the gain has been made on a less fuel. Interesting to see how she goes on E85

I know this isn't the forum to ask this....but,
Did you cut and shut rb runners or use adapter plates for the itbs? Pics?
Awesome result man

Ebay™  Cheapo build part 2:

Rb25det S1 200,000kms and low compression 120-130psi average, had a blown headgasket never fixed it, just put headgasket stop leak in it over a year ago - $650 off ebay

ebay no name 740cc injectors - $180

ebay walbro 460 - $150

r32 gtr intercooler - $100

ebay electronic boost controller 'd2power' - $80

2nd hand nistune ecu $250 + feature pack $55

hypergear 21u g3 highflow - $950

Very happy with full boost coming on at 3700rpm. Was using the stock 7psi actuator so the maxed out boost controller was only giving us 17psi. With vct and e85 the power comes on hard as. Blue line is e85 (actually around e65)

All, 

people that have hyper gear hybrid for r34 gtt, is it quite laggy?

 

mine lags and only responds after 3.5k

 

feels very weak and on ceramic one it was very responsive
