*VIDEO* - HIGHER BOOST - Crispeed Tuned 1st Gen
 

Well, from the last time I went to the dyno a few weeks ago, We were able to get 409 RWHP at 14 PSI. This was documented In this thread.<IN this Thread><HERE, thread this in>

Back then, we couldn't raise the boost higher than 14psi, otherwise the ignition was breaking up. When we returned, the problem persisted - until we found out the dyno ignition pick up wire was actually causing the cross-fire. Crap!

Well, once we eliminated the dyno RPM signal wire, we were able to increase the boost:

Numbers are:

• 336 at 9 psi (pump gas)
• 409 at 14 psi (pump gas)
• xxx at 18 psi (pump gas)
• XXX at 21 psi (C-16)

The car:

• 1985 RX-7 GSL-SE
• Haltech E6K -Tuned by Crispeed
• 63-1 Turbo
• Ford 8.8 Rear End (very heavy!)
• Isuzu NPR Intercooler (Large)
• 720's & 1600's
• Aeromotive 1000

Here's the video of it all:
High Resolution (89 megs) right click, and Save-As <-Thanks Vosko!
Low Resolution (Streetfire) <-56K Only (should be working soon)

Let me know what you think.

I'll post a full dyno sheet soon. The engine is definately capable of more power - We just ran out of wastegate spring. We could't run more than 20psi. Even with the Profec B set all the way. I have a 9lb spring in the Wastegate, and really should be runninng a 14+lb spring to enable higher boost.

It's all good though, and I am verrry happy with the performance, Especially
from a relatively small turbo - deisgned for street use, quick spooling.

Once again - Thanks Chris.

Holy shit your car= burly.

its a movie from TLC....

I don't get it.:confused:

so what were the high boost #s?

Very nice car man. You are an inspiration to all rotary owners, not just first gen.

impressive, this can really fuck with the v8's

Just Wow. That car is very impressive. Incredibly well put together. The fact that it's a 480rwhp SE is just icing on the cake. Keep it up man, awsome job!! :bigthumb:

457HP @ 18psi on pump gas :eek: :bigthumb:

480HP @ 21psi (C16?)

Congrats on those numbers!!

Watch the movie!!

:eek: :eek: :eek: Folks tell your kids to stay off the sidewalks..
Very nice car..gorgeous inside and out. Great numbers :bigthumb:

I wish my GSLSE was like that why dont you guys open a shop in NJ

How much does the car weigh?

6 point steel cage, 1/2 a tank of gas, everything in it (except me) = 2650.
Without the side bars (making a 6 point into a four point) it's probably 50 lbs lighter.

This is with the stock rear end - I haven't weighed it with the new rear.

I'd guess around 2700 fully loaded.

Very nice!!

Very nice! Congrats.

did you blow the rear end or something??? on the vid, where you running the 1/4 mile on it?? if so, what did it tell you?

Nice! I'm jealous.. I can't wait to get to work tomorrow so I can watch that vid (still 56k here at home). How does it feel on the street with 480RWHP? I can only imagine... My buddy ran a 11.24 @ 123mph yesterday with 485BHP in a 2800# FC. I smell 10's in your future :D

How's the spool, when does it make full boost?

Spool is excellent. Especially with the haltech over the old holley system. Full boost by 4100 rpm. This turbo is very similar in specs to the GT35/40

Incrediable vid! Excellent power results. Always nice to see what qualified tuners can do! Big thumbs up to Crispeed.

Great job on the car and video; they leave nothing to question on the abilities of all involved. Simply outstanding!

Awesome video and awesome car.

Just a little side questions, What is the limit in boost for C-16, roughly? 25psi? 30psi?

Great video!! It was very well put together and edited flawlessly. On a more important note your car is INCREDIBLE!!!! You should be very proud. You've built a very clean and powerful car. One of the best 1st gens I've ever seen.

Zach

Awesome. You guys are incredible. What a freakin 1st gen !!!
I am tired, and very jealous.
