Project: Ultimate Response GTS-T

[cschepp]

Cool klys that's awesome man. Oh ya btw thanks for the stud number I ordered them up from nissan the only down fall was that they took 2 weeks to come in, but they worked awesome. My cars going back together and soon hope to get this close to finished. Its killing me not driving it in this beautiful weather!

[klys]

Well the build is now finished for the summer.

I went to the dyno yesterday and managed 350WHP@6000RPM and a steady 16psi :P


Boost control is good, no more over boosting .. got like 50HP by going there and smoothing things out!

I also fixed a very strange dip in torque that was caused by the timing being pulled from 21 to 7 ... ?! that 14 deg retard caused us alot of trouble but I finally found out to fix it.


Injectors reach 76% which is still very safe
dynosheet to come
the tuning was done on a dynapack dyno at dynodoc in outremont
hey was very well equiped and things went smoothly once we got everything sorted out

[frankiman]

nice numbers !!!

your car is going to be hella fast - er than mine..

did you tune it yourself?

I like. 400hp at engine is going to make it a quick R32GTS-T on the racetrack.

[klys]

Here's the dynosheet

[Skym]

I like. What does the boost curve dynochart look like??, as it looks like turbo achieves full boost just over 4000rpm (about 4200rpm), going by when engine reaches peak torque, which is not bad. Much better than stock GTS-R turbo at 4800rpm.

Boosted up stock GTS-R achieves around 284rwkw (380.8rwkw) at 22psi. So 265rwkw (355rwhp) at 16psi on your car is not bad when you consider your car has a stock exhaust manifold and GTS-R has the hp advantage of a equal length exhaust manifold. There's like a 12hp+ gain at same boost level with equal length exhaust manifold.

Does your engine have cams???

[klys]

I got the csv data so I'll post it up :P

yes it has cams

I think the 2.2L makes a difference compared to the 2.0L from the GTS-R



as you can see the slight over boost seems to be good, and the little dip at 4500 could give a few more HPs

also AFRs at 3000 ned to be a bit more rich to help spool things up I think.



PS here's the Dyno sheet from Oct. 2005 where the power is flywheel estimate

I think RPM seems strange.... don't remember what technique they used back then.

with the dynopack, engine was brought up to the 3500RPM on the AVC-R and the ratio was determined

all pulls were done in 4th gear

with an R34 RB20DE tranny

[Skym]

So dyno run was done in 1:1 gear of the R34 RB20DE gearbox???

I gather from dynograph of RB30 vs RB26 that throughout powerband is where the 2.2 litre would help.

I was told by my tuner mate that a dip at lower rpm's is due to duration of cams and gets worse with more duration and is totally normal, as I gather cams require engine to be run richer at idle, etc. That's the only downside to cams. My guess is Tomei Poncams (going by shape of curve compared to dynochart's I've seen with Tomei Poncams installed)???

[klys]

Well it would make sense as the engine was built by Tomei in 1998

it was a lot of fun chasing you around the track yesterday man, i gotta say, given all the power that was at the track that day, i could not keep up with you!!!!

you have changed my view point on the GTS-T... i never imagined it could be SO quick and SO agile... bravo on building an incredible car bud, and thanks for teaching me a thing or 2!!

I'm glad you enjoyed your ride.

I didn't know if I needed to wait for you guys, but tought it would be more fun if I did drive 80-90%
especially after the change of tires and the spark plugs MitchR32 gave me. Wow the car never ran that good!

heheh Well as you know I need a transmission by then.

Almost got one, but it was already sold

[archaeic_bloke]

thought you might wanna see this. let it fully load first so its smooth rolling...

that is all, enjoy!

[klys]

Well The car is in storage but I managed to get the new tranny in!!

car's gonna be ready for next year!
