It's been awhile since I've posted anything worth mentioning so I hope this would be pleasing to many of you guys.

Here is one of Inline Racing's H22 Turbo Prelude. We just tuned my new turbo set this weekend and it pushed out 487WHP & 333WTQ on 93 Octane at 20 PSI of boost, WITH AC!!

Engine building, fabrication, & tuning was done by Huy @ Inline racing.

Pictures:- Most of the pics I have are from the work in progress. Once I clean everything up, I will take better pics and update, but this should do alright for now.

 

We will be putting the car on race gas next week to see how it does. I will post the results once they are collected .

 

Man.. awesome stuff. Is there a reason you chose 8.5:1 compression pistons? I love the fact that you tunned off crome. Crome ftw! Nice setup man. I will hopefully break 400whp with my SC61 shortly.

 

Nice work man.. Very nice with AC!

Slowly guys here are getting their builds completed... Slowly...

 

Looks good

 

greatness

 

sweet set up and on your number

 

What's up with the spiky/peaky hp and tq curves? Boost fluctuation? Ignition break up? Poor tuning?

You must have one of those ultra rare 5 cylinder H22's!

j/k. Setup looks really good! I'm curious to see how those pressed in cylinder liners hold up to more whp.

 

Very nice man. Soon i will be pushing my car to get some where near the 400's

 

Big inspiration to us that are working on boosting our cars. Nice numbers man! Keep us posted.

thats the first thing that came to my mind.

not hating, just doesnt appear that the motor is very efficient.

I was wondering the same thing. The first thing i saw was the curve and from what im looking at she isnt very efficient at the moment. Its almost like its breaking down durring the run. Could be many things on a new build TELL THE MECHANIC TO DO WHAT HES GETTING PAID FOR! give us an update on the problem !!!!! OVERALL THOUGH I GIVE IT nice build.

Ditto. I'm not hating or trying to start a pissing thread but the motor should be doing much better. Here is a chart from a gt35r built h22a that we did at 20psi to give you an idea of what everything should look like:



The run was cut off at 7500rpms because we were getting false readings on the injector duty cycle. This is why we didn't go with more boost... we thought we were maxing the injectors out. Anwyays, 1600cc's are going in and hopefully she'll put out 600+ out.

Dyno graph looks nice And no offense taken.

The spikes/peaks you see if due to boost fluctuation. We had a small hole in the hot side charge pipe that my AC compressor was rubbing against and wore a small hole in it.

This motor also has an unported head as well, I feel that that is now the major choking point of the entire setup.

We would first like to get some data on how it does on 110 octane, then we'll port the head and put in 1mm oversized valves on the intake and .5mm on the exhaust.

Thanks for the comments guys

I thought it was boost fluctuation.... that will always ruin a dyno chart. The drag manifolds tend to produce somewhat of a similar dyno chart on the H series that I've worked with.

The H22a that we did was done on 93 octane but I didn't know it was making that much power when I was street tuning it. So once the first run was done we dumped 110octane in it. Again, we had false readings with the injector duty cycle so I didn't even get to play with the cam gears or ignition timing because I was afraid of going lean.

Also, with your tune on race gas you'll be able to lean it out a bit. 11.0-11.3:1 is a tad bit on the rich side. Again, it's safe but it will not help obtaining a nice smooth power/tq curve.

Very true, my tuner likes to be very conservative with the tune since we are still on pump gas.

Overall I am very impressed with the setup and the power it's making on pump gas. I couldn't ask for more, especially with the non ported head and very basic setup, nothing that fancy.

 

Sick velocity stack.. lol.

You could probably get more but 487 to the wheels is pleeeenty for a Prelude.

Thank you, I felt that would be the perfect finishing touch to the setup

 

Hmm... you got me thinking about those pressed in Iron liners

cheaper than sleeving tell u that but man i dunno im not sold on em yet

 

Got any more info on these Dfw?

 

cool too see the liners doing this so far!

I will say I doubt the head not being ported hurts much, GregH is pushing 528 at 15 psi on stock head, only springs and retainers are not stock.

Granted that a turbo setup does not see as much of a HP gain as an all motor setup from a ported head, but from my experiences in the past, we've gained a decent amount of HP from a ported head with the same boost pressures. I hope that we'll see the same gains when we port this head with oversized valves. We'll let the dyno graphs speak for itself when we do so.

I am very impressed with the liner's performance as well. I am hoping I may be able to change some minds with these tests and results.

 

how much of an ignition retard are you running? from my readings of crome, adding ignition isnt so much of a problem as removing timing (excessively)
